It's an example of associative property of addition.
Answer:
4x.
Step-by-step explanation:
If the scale factor is 2 then the area factor is 2^2 = 4.
So the area of the new triangle is 4*x.
The person with the 5 gets 30 and the person with 4 gets 24
(a+b)(a-b)=a^2 - b^2
so
<span>(4x-7)(4x+7) = 16x^2 - 49
answer
</span>16x^2 - 49
Yeah i believe this question is a error!!if not it should be 88
