Step-by-step explanation:
distributive property
9(2j + 7 + 5j)
9× 2j + 9×7 + 9 × 5j
18j + 63 + 45j
associative property
9(2j + 7 + 5j)
9(2j + 7) + 9(5j)

I NEED HELP FAST PLEASE! Find the surface area of the following composite figure.
the answer is 228 I was wrong when I said
I think the choices is wrong
Answer:
B. 228 meters square
Step-by-step explanation:
6 x 4 = 24
24 x 4 = 96
6 x 6 = 36
(8 x 6) / 2 = 24
24 x 4 = 96
96 + 96 + 36 = 228 square meters

Jada, Diego, and Elena each use the same spinner that has four (not necessarily equal sized) sections marked A, B, C, and D.
Answer: 1. Jada’s method is the most accurate. 2. None of the methods match the 1/4 probability exactly because it’s the real world and it is still up to chance.
Step-by-step explanation: 1. Jada spun the most times, and accuracy increases with how often something is tested.
If some one could PLEASE help me with my math, that would be excellent!

6 is likely
7 is impossible It is impossible since there are no 6-inch pliers in the second basket.
Jada, Diego, and Elena each use the same spinner that has four (not necessarily equal sized) sections marked A, B, C, and D.
Answer:
Diego is the most accurate, the probability of landing on B is 25% and he guessed 20% which is the closest to 25%
None of them match exactly because since they are not all equally sized, there is no way of telling exactly what the probability of landing on the sections are.
I hope this helps and sry if its wrong!

Tell whether the difference between two negative integers is always, sometimes, or never positive. The difference between two negative integers is (blank) positive. Question 2 Explain your reasoning. 1) It’s always positive because the first integer is always greater. 2) It’s positive only if the first integer is greater. 3)It’s never positive because the first integer is never greater. HELP QUICK!!!!!!!! ITS DUE TODAY (NO LINKS OR YOU WILL BE REPORTED)
Answer:
. 2) It’s positive only if the first integer is greater
Answer:
Step-by-step explanation:
The difference is sometimes positive. If the second number is smaller than the first, then the result will be positive..
Example
-4 - - 6 = -4 + 6 = 2 which is positive.
Remember - 6 is smaller than - 4. Think money. Which would you rather be: 4 dollars in the whole (-4) or 6 dollars in the whole (-6)?

At a concert 6 out of the first 20 people who entered the
concert were wearing hats. Based on this information, if
there are 800 people at the concert, how many of these
people are expected to be wearing a hat?
Answer:
240 people
Step-by-step explanation:
6/20=x/800
800*6=20x
4800=20x
240=x
Therefore, you would expect 240 people to be wearing a hat

For a triangle with length of its sides of 5, 13, and 14, determine if it is a right triangle.
Answer:
it's not a right triangle
Step-by-step explanation:
5² + 13² = 14²
=> 25 + 169 = 196
=> 194 ≠ 196
The length of the triangles is 5 units , 13 units and 14 units and it is not a right angled triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measures of the sides of the triangle are 5 units , 13 units and 14 units
And , To determine if the triangle with sides 5, 13, and 14 is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.
If the theorem holds true for the given triangle, then it is a right triangle.
Let's check:
5² + 13² = 25 + 169 = 194
14² ≠ 194
Since 5² + 13² is not equal to 14², the triangle with sides 5, 13, and 14 is not a right triangle.
Hence , the triangle is not a right triangle

Solve 4/9 plus x =7/9 x =
Answer:
x = 1/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x + 4/9 = 7/9
Step 2: Subtract 4/9 from both sides.
x + 4/9 - 4/9 = 7/9 - 4/9
x = 1/3
Answer:
x = 1/3 (or) 3/9
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ (4/9) + x = 7/9
Then the value of x will be,
→ (4/9) + x = 7/9
→ x = (7/9) - (4/9)
→ x = (7 - 4)/9
→ x = 3/9
→ [ x = 1/3 ]
Hence, the value of x is 1/3.

Answer:
28.3
Step-by-step explanation:
Answer:
28.3
Step-by-step explanation:
Use the Pythagorean theorem a^2 + b^2 = c^2
x is a, 17 is b, and 33 is c
x^2 + 17^2 = 33^2
Simplify:
x^2 + 289 = 1089
Subtract 289 from both sides:
x^2 = 800
Square root both sides:
x = √800
√800 is 28.28427, or 28.3
Jessica rented 1 video game and 3 movies for a total of $11.50.
• The video game cost $4.75 to rent.
• The movies cost the same amount each to rent.
What amount, in dollars, did Jessica pay to rent each movie?
Answer:
1 video game = 4.75
1 movie = x
4.75 + 3x = 11.50
-4.75 -4.75
______________
3x = 6.75
(3x = 6.75) ÷ 3
x = 2.25
Jessica paid $2.25 for each movie she rented.

I hope this helps :)
Answer:
$2.25
Step-by-step explanation:
11.50 - 4.75 (gives you the total amount of MOVIES rented)

The circumference of a circular garden is 128.74 feet. What is the diameter of the garden? Use 3.14 and do not round your answer.
Answer:
41 feet
Step-by-step explanation:
For a radius r, the circumference is [tex]2\pi r[/tex] and the diameter is [tex]2r[/tex], so to get diameter, we can just divide the circumference by pi and we get the answer. Using 3.14 for pi we get:
[tex]127.74 / 3.14 = 41[/tex]
