Answer:
The first thing you ever do when simplifying an expression is distributing the coefficient. For example the expression 3(5x+6+4x) The first thing we would do is distribute the 3 into each value in the parantheses. It would make sense to add the 4x and 5x, but that goes out of order. This is just the rules when it comes to follwing distributive property in it's simplest form.

Answer:
∠1 = 103°
Step-by-step explanation:
supplementary angle to 136° = 180° - 136° = 44°
∠1 = 180° - 33° - 44° = 103°
Step-by-step explanation:
Let the unnamed angle in the triangle be x.
x + 136 = 180 (Sum of angles on the same straight line)
x = 180 - 136
= 44
Angle 1 + x + 33 = 180 (Sum of angles in a triangle)
Angle 1 + 44 + 33 = 180
Angle 1 + 77 = 180
Angle 1 = 180 - 77
= 103
An architect is constructing a model in the shape of a triangle that has one side length of 9 centimeters and another side length of 8 centimeters. Which
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Sides:\ 9cm\ and\ 8cm[/tex]
The question is incomplete, as what is required is not state. However, a possible question could be to determine the possible side length of the third side.
To do this, we make use of the triangle inequality theorem which states that:
Given three sides (a, b and c) of a triangle, the following inequalities exist.
[tex]a + b > c[/tex]
[tex]a + c > b[/tex]
[tex]b + c > a[/tex]
Let a and b represent the two sides such that:
[tex]a = 9[/tex]
[tex]b = 8[/tex]
The inequalities become:
[tex]9 + 8 > c[/tex]
[tex]9 + c > 8[/tex]
[tex]8 + c > 9[/tex]
Solve for c in each:
[tex]9 + 8 > c[/tex]
[tex]17 > c[/tex]
[tex]c < 17[/tex]
[tex]9 + c > 8[/tex]
[tex]c > 8 - 9[/tex]
[tex]c > - 1[/tex]
[tex]8 + c > 9[/tex]
[tex]c >9 - 8[/tex]
[tex]c >1[/tex]
The value of c must be positive, so, we consider;
[tex]c >1[/tex] and [tex]c < 17[/tex]
Rewrite:
[tex]1 < c[/tex] and [tex]c < 17[/tex]
Combine both
[tex]1 < c < 17[/tex]
Hence, the value of c is:
[tex]c = (1,17)[/tex]
Calculate the area of the shape below:
6 in
6 in
12 in
O 54 in?
0 432 in?
O 216 in
O 108 in?
Answer:
54
Step-by-step explanation:
The square in the middle = 36, as 6x6=36
There are 2 triangles on each side of the center square.
Since the base of the trapezoid is 12, and the base of the square is 6, that leaves 3 for the base of each triangle.
3x6=18x1/2 (As a triangle's area is b (base) x h (height) x (one half) 1/2
18x1/2 is 9.
Each triangle equals 9.
36+9+9=54
The final answer is 54

Answer:
7u -63
Step-by-step explanation:
The distributive property says you can eliminate parentheses by applying the outside factor to each term inside parentheses.
(u -9)7 = (u)(7) +(-9)(7) = 7u -63
Answer:
(u -9)7 = (u)(7) +(-9)(7) = 7u -63
You are drawing a map of your school and want to make sure all the measurements are accurate. You decide to use a scale of 1 cm = 3 feet. In your drawing, the main hallway ends up being 12 cm long.
The drawing is a little too big so you decide to change the scale to 1 cm = 4 feet.
Keeping the length in feet the same, how many centimeters long should the main hallway be in your new drawing?
Answer:
the main hallway should be 12cm in the new drawing

Answer:
6 + 4d + 11c
Step-by-step explanation:
In order to find the perimeter, you add up all the side lengths which would be expressions in this case
(10c + 10) + (c + 5) + (4d - 9)
add like terms: (10c + c) + (10 + 5 - 9) +4d
= 11c + 6 + 4d
which is the same as 6 + 4d + 11c, I just added them in a different order.

The area of a square playground (in square feet) can be represented by x2 - 30x + 225. How many feet is the perimeter of the playground if x = 25?
Answer:
40
Step-by-step explanation:
Substitute 25 for x
[tex] {25}^{2} - 30(25) + 225 = 100[/tex]
100 is the area of the square so that means
10 is the side length of each side of the square.
Multiply 4 by 10 to get the perimeter.
[tex]4 \times 10 = 40[/tex]

NO LINKS!! PLEASEE HELPP QUICK I POSTED THIS SO MANY TIMES AND NOBODY ANSWERS PLSSS HELP MEEE Write the slope-intercept inequality for the graph below. If necessary, use <=
fors or >= for >
Answer:
y ≤ -2x - 2
Step-by-step explanation:
Slope- intercept form is y = mx + b, m being the slope and b being the y-intercept.
The slope is the rise of the line over the run. We can choose two points that are exactly on the line. Let's try points (-1, 0) and (0, -2). The line slopes down, so we already know the slope is negative. From point (-1, 0), the line goes down 2 units and over 1 unit. So, the slope is -[tex]\frac{2}{1}[/tex]. We can also simply say that the slope is -2.
The line intersects with the y-axis at point (0, -2), so the y-intercept is -2.
Because the shading is on the left side of the line and the line is solid, we can tell that y is less than or equal to -2x - 2. So, the equation is-
y ≤ -2x - 2

What is the answer to c to the fifth power, times c to the eighth power, times c to the negative fifth power?
Answer:
c^8
Step-by-step explanation:
Expressing the above Mathematically ;
c^5 * c^8 * c^-5
From.rules of indices :
a^x * a^y = a^(x + y)
Therefore, applying the rule of indices ;
c^5 * c^8 * c^-5 = c^(5 + 8 + - 5)
c^5 * c^8 * c^-5 = c^(5 + 8 - 5)
c^5 * c^8 * c^-5 = c^8
Hence,
c^5 * c^8 * c^-5 = c^8
A man started a journey at 09:30 h and arrived at his destination in the same time zone, at 13:30 h on the same day. If his average speed was 30km/h, then the distance, in km, for the journey was
Answer:
120km
Step-by-step explanation:
We multiply 30km (thats how fast he was moving per hour) by the number of total hours during the journey, which is 4, 30 x 4 is 120km.
After applying the distributive property to the expression 8(12-4) and then multiplying what will be the first term in the resulting subtraction expression
Answer:
The first term in the resulting subtraction expression is 96.
Step-by-step explanation:
Given - After applying the distributive property to the expression 8(12-4) and then multiplying
To find - What will be the first term in the resulting subtraction expression ?
Proof -
Given the expression is -
8( 12 - 4) = 8(12) - 8(4)
= 96 - 32
⇒8( 12 - 4) = 96 - 32
So,
The first term in the resulting subtraction expression is 96.
What’s the probability?
Answer:
[tex]\frac{1}{8}[/tex]
Step-by-step explanation:
The probability for a flip on either side of the coin is always 50% or [tex]\frac{1}{2}[/tex]
So to get the probability for the three flips just do:
[tex](\frac{1}{2}) ^{3}[/tex] or [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex]
Either way you solve it the answer is [tex]\frac{1}{8}[/tex]

The two legs of a right triangle measure 7 inches and 5 inches. Find the measure of the acute angle that is included between the longer leg and the hypotenuse. WILL GIVE BRAINIEST TO FIRST RIGHT ANSWER
Answer:
44.4 degrees
Step-by-step explanation:
Given the following
Hypotenuse = 7
Longer leg = 5 (adjacent])
Let the acute angle angle between both sides be x
According to SOH CAH TOA
Cos theta = adj/hyp
Cos x = 5/7
x= arccos (5/7)
x = arccos (0.7143)
x = 44.4degrees
Hence he measure of the acute angle that is included between the longer leg and the hypotenuse is 44.4 degrees
