Hey there!

First off, I’m going to assume that the 2 in the second term is an exponent. If it isn’t, let me know and I’ll fix the answer.

Anyways, let’s start by plugging the values for the variables into the equation.

36(3)-8(-6)^2

Square -6

108-8(36)

Multiply.

108-288

Subtract.

-180

Your answer is -180.

Hope this helps!

Given △ABC where A(2, 3), B(5, 8), C(8, 3), RS is the midsegment parallel to AC, ST is the midsegment parallel to AB, and RT is
soldier1979 [14.2K]
Since RS is a midsegment parallel to AC, that means R is the midpoint of AB and S is the midpoint of BC.  The midpoint formula is:
(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}).  Using the coordinates of A and B, we have:
R=(\frac{5+2}{2},\frac{8+3}{2})&#10;\\R=(\frac{7}{2},\frac{11}{2})&#10;\\R=(3.5, 5.5).  Similarly, S is the midpoint of BC:
S=(\frac{5+8}{2},\frac{8+3}{2})&#10;\\S=(\frac{13}{2},\frac{11}{2})&#10;\\S=(6.5, 5.5).
Since ST is a midsegment parallel to AB, then T must be a midpoint of AC:
T=(\frac{2+8}{2},\frac{3+3}{2})&#10;\\T=(\frac{10}{2},\frac{6}{2})&#10;\\T=(5,3).
Now that we have the coordinates of each point we can find the length of each segment using the distance formula:
d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
For ST:
d=\sqrt{(6.5-5)^2+(5.5-3)^2}&#10;\\=\sqrt{(1.5)^2+(2.5)^2}&#10;\\=\sqrt{2.25+6.25&#10;&#10;\\=\sqrt{8.5}=2.9 \neq 4
For RT:
d=\sqrt{(3.5-5)^2+(5.5-3)^2}&#10;\\=\sqrt{(-1.5)^2+(2.5)^2}&#10;\\=\sqrt{2.25+6.25}&#10;\\=\sqrt{8.5}=2.9 \neq 5
For RS:
d=\sqrt{(3.5-6.5)^2+(5.5-5.5)^2}&#10;\\=\sqrt{(-3)^2+(0)^2}&#10;\\=\sqrt{9+0}=\sqrt{9}=3
