If QRST is a rectangle with QT = 30 and RS = 4x + 10, find x.

1 answer:

4 0

The opposite side pairs in a rectangle are congruent, so basically QT would be congruent to RS when you draw the rectangle and label the points.
4x+10=30
4x=20
x=5

$\overline{XY}=\overline{XZ}=\overline{ZY}\\\\
\dfrac{1}{2}x+8=2(x-8)\\
\dfrac{1}{2}x+8=2x-16\\
x+16=4x-32\\
3x=48\\
x=16\\\\
2(16-8)=2\cdot8=16\\\\
\overline{XY}=16

Just replace each variable to what it is equal to. For example, replace the a variable in ab + cd with 2.

2 * -3 + 4 * -5 =

First, do the multiplication.

2 * -3 + 4 * -5 =
-6 + -20 =

Add up.

-6 + -20 = -26

So, the answer to this question is -26.
