Answer:
(x + 9)(x - 5)
Step-by-step explanation:
x^2 + 4x - 45
factorising by using middle term break method
=x^2 + (9 - 5)x - 45
=x^2 + 9x - 5x - 45
=x(x + 9) - 5(x + 9)
=(x + 9)(x - 5)

Answer:
Step-by-step explanation:
Tangents from the point outside the circle are equal.
x + 7 = 13 +8
x + 7 = 21 {Subtract 7 from both sides}
x = 21 - 7
x = 14
How do I solve -11+9=2x+45?
Answer:
x = - [tex]\frac{47}{2}[/tex]
Step-by-step explanation:
Given
- 11 + 9 = 2x + 45 , that is
- 2 = 2x + 45 ( subtract 45 from both sides )
- 47 = 2x ( divide both sides by 2 )
- [tex]\frac{47}{2}[/tex] = x

Edward went to the market with Rs 4x 2+y2+3y and spends Rs 2x 2+y for a packet of chips and chocolate for the remaining money. How much is the cost of chocolate?
Answer:
Edward spent Rs 2[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + 2y on chocolate.
Step-by-step explanation:
Initial amount with Edward = Rs 4[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + 3y
The cost of a packet of chips = Rs 2[tex]x^{2}[/tex] + y
By assuming that Edward spent all his money at the market, and on both chips and chocolate. Then;
Amount spent on chocolate = Initial amount with Edward - cost of a packet of chips
= (Rs 4[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + 3y) - (Rs 2[tex]x^{2}[/tex] + y)
= Rs (4[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + 3y - 2[tex]x^{2}[/tex] - y)
= Rs (4[tex]x^{2}[/tex] - 2[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + 3y - y)
= Rs 2[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + 2y
Amount spent on chocolate = Rs 2[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + 2y
Therefore, Edward spent Rs 2[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + 2y on chocolate.

The figure above shows a circle with center Cand
radius 6. What is the sum of the areas of the two
shaded regions?
160
С
Answer:
Sum of the areas of two shaded regions = 100 unit² (Approx.)
Step-by-step explanation:
Given:
Radius of circle = 6 units
Angle of one unshaded area = 160'
Find:
Sum of the areas of two shaded regions
Computation:
Angle of one shaded area = 180' - 160'
Angle of one unshaded area = 20'
Sum of the areas of two shaded regions = 2[θ/360][πr²]
Sum of the areas of two shaded regions = 2[160/360][(3.14)(6)²]
Sum of the areas of two shaded regions = 2[160/360][(3.14)(36)]
Sum of the areas of two shaded regions = 2[160/360][(3.14)(36)]
Sum of the areas of two shaded regions = [0.888][113.04]
Sum of the areas of two shaded regions = 100.46
Sum of the areas of two shaded regions = 100 unit² (Approx.)

I don’t know what to do?
Answer:
I geuss because the scale factor is 2 that the resulting triangle will be almost twice the size. Because in a dilation you multiply it. If you dont know how to dilate a triangle with a compass I would suggest looking for a video online. But I know for the part that says "Is the image of ABC similar to the original triangle" the answer would be yes it is similar because you are just dilating the triangle not changing its orientation. I hope this helps! Good luck!

Answer:
x = 2.5
Step-by-step explanation:
We know the adjacent and the opposite sides to the angle in a right triangle
tan theta = opp / adj
tan 26 = 1.2 /x
x tan 26 = 1.2
x = 1.2 / tan 26
x =2.46036461
Rounding to the nearest tenth
x = 2.5
tan tita = opp/adj
tan 26°=1.2/x
x=1.2/tan 26
x=2.46
x=2.5

Write an equation for a line that is perpendicular to the line 6y – 9x = 12
Answer:
y = -2/3x + 4
Step-by-step explanation:
first we take the original equation and convert it to y=mx+b (a form we know how to graph)
that gives us y = 3/2x + 2
(Here's my work for that):
6y - 9x = 12; add 9x on both sides
6y = 9x + 12; divide 6 on both sides
y = 9/6x + 12/6
y = 3/2x + 2
next to make a line *perpendicular* to this, we make the slope negative and swap the fraction (-2/3)
then we just uh graph that slope and try to find the y intercept. i did it already and i got 4
Answer:
Step-by-step explanation:
You need one more piece of information to get a specific line. I'll get the general one and then we'll see what comes of it.
Add 9x to both sides.
6y - 9x + 9x = 9x + 12
6y = 9x + 12 Divide by 6
6y/6 = 9x/6 + 12/6
y = 1.5x + 2
Now the perpendicular line must have a slope that is found by using
m1 * m2 = - 1
m1 = 1.5 From the equation above.
1.5 * m2 = - 1 Divide by 1.5
m2 = -1/1.5
m2 = - 2/3
So far what you have is
y = -2/3 x + b You need a value for b. Usually that is found with a point. But I will just call b = 1 since there is nothing else to do
The complete equation becomes
y = -2/3 x + 1
The graph is enclosed.

Runelle collected river water for an experiment. She poured it into 8 jars. Each jar had the mixed number two and three fourths pints of water. What is the total amount of river water Runelle collected?
Answer: 22 pints of water
Step-by-step explanation:
Runelle collected river water and poured in eight jars such that each jar had 2³/₄ of water.
The total amount of water collected by Runelle from the river will therefore be the sum of all the water in the 8 jars and because they are the same, we can simply multiply the quantity in one jar by 8 to see the sum:
= Amount of water in one jar * 8 jars
= 2³/₄ * 8
= 11/4 * 8
= 22 pints of water
