The answer is the distributive property because it states that if you have a number multiplied by a quantity, you can just multiply that number by each of the terms in the quantity. For example, a(x+y)=ax+ay.
Hope this helps!
Answer:
<h2>A = 3x²</h2>
Step-by-step explanation:
The formula fo an area of a triangle:
![A=\dfrac{bh}{2}](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7Bbh%7D%7B2%7D)
b - base
h - height
We have
x - base
6x - height
Substitute:
![A=\dfrac{(x)(6x)}{2}=\dfrac{6x^2}{2}=3x^2](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B%28x%29%286x%29%7D%7B2%7D%3D%5Cdfrac%7B6x%5E2%7D%7B2%7D%3D3x%5E2)

Answer:
x = -4, y = -2
Step-by-step explanation:
substitute for y
2x - 5(x + 2) = 2
distribute -5
2x -5x - 10 = 2
solve
-3x - 10 = 2
add 10 on both sides
-3x = 12
divide by -3
x = -4
now substitute for x in the equation y = x + 2
y = -4 + 2
y = -2
