Answer:
7
Step-by-step explanation:
Because it is asking what X value are all the functions equal to just find a point that lies on X that they all come to.
In this case it's 7
<u>x = 7</u>
The functions are equal to each other where the lines of the functions intersect each other.
The intersection point is (7, 3).
The x-value at this point is 7.
Hence, <u>x = 7</u>.

I think is number A
What do you Think?
V=1.3(repeating)A+1.3(repeating)M
8x² + 8
Given
(x² + 3)² - (x² - 1)² ← expand both factors using FOIL
= + 6x² + 9 - ( - 2x² + 1) ← distribute by - 1
= + 6x² + 9 - + 2x² - 1 ← collect like terms
= 8x² + 8
