Your answer is 4x + 18.
Step-by-step explanation:
QR = 5x - 3
RS = 21 - x
Now,
QS = QR + RS

= 5x - 3 + 21 - X
= 4x + 18 (Answer.)
Answer: 91
Step-by-step explanation:
the equation to find the area of a trapezoid is as follows:
A = (a+b)/2h
So A = 6+20 which is 26
then you divide 26 by two which gives you 13, then multiply by 7
√64=8 ∛8=2
In the √, you find something that squares into the number
In the ∛, you find something that cubes into the number
