I believe that the answer is AA similarity (A).
I think it’s 9.10 but I’m not really sure
There is no rate of change of Function 1. It's slope(rate of change) is zero.
Function 2 has a slope of 2.
<span>x^2 + 8x = -3
</span><span>x^2 + 8x + 16 = -3 + 16
using a^2 + 2 a b + b^2 = (a+b)^2
</span><span>
</span>x^2 + 8x + 16 = 13
<span>(x +4)^2 = 13
answer : 16 is the number </span><span>you must add to complete the square</span>
Never seen the exact thing before
But if I’m not mistaken
a should be the number before x^2
b is before x
c is the last number
including the negative sign!
