Answer two questions about Equations AAA and BBB: \begin{aligned} A.&&3(x+2)&=18 B.&&x+2&=18 \end{aligned}
A.
B.




3(x+2)
x+2


=18
=18


1) How can we get Equation BBB from Equation AAA?

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

a. the residual plot for model 1 has a random pattern and is a good fit for the data.
