Expand. If necessary, combine like terms. (x+7)^2

=x ^2+14x+49

Step-by-step explanation:

left parenthesis, start color #11accd, a, end color #11accd, plus, start color #ed5fa6, b, end color #ed5fa6, right parenthesis, squared, equals, start color #11accd, a, end color #11accd, squared, plus, 2, start color #11accd, a, end color #11accd, start color #ed5fa6, b, end color #ed5fa6, plus, start color #ed5fa6, b, end color #ed5fa6, squared

Hint #22 / 2

Using the above pattern, we get:

\begin{aligned} &\phantom{=}(\blueD x+\maroonC 7)^2 &=\blueD x^2+2(\blueD x)(\maroonC 7)+\maroonC 7^2 &=x^2+14x+49 \end{aligned}

=(x+7)

2

=x

2

+2(x)(7)+7

2

=x ^2+14x+49

x + 4/7

step-by-step explanation:

use cymath

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
