2x+10 = -2(X-5)
Distribute the parenthesis 
2x+10 = (-2X)- 10
<span>add the ten on the right side
</span>2x+20 = -2X
<span>divide the 2 on the left side from the x
then you get 20=x or x=20

First distribute -2 to both x and -5

-2(x) = -2x
-2(-5) = 10

2x + 10 = -2x + 10

False. 2x + 10 ≠ -2x + 10

False is your answer

hope this helps

harina [27]

Answer:

  24.0 square feet

Step-by-step explanation:

The area of the sector is given by ...

  A = (1/2)r²θ . . . . . where θ is the angle in radians

The area of the circle is the same, with θ=2π, so is ...

  A = πr²

__

In this problem, the area of the sector is ...

  A = (1/2)(9 ft)²(24π/180) = 27π/5 ft² ≈ 16.9646 ft²

The area of the circle is ...

  A = π(1.5 ft)² = 9π/4 ft² ≈ 7.0686 ft²

Then the total area of the exclamation point is ...

  16.9646 +7.0686 ≈ 24.0 . . . ft²

The area is about 24.0 square feet.
