Step-by-step explanation:
the area of this rectangle is
(10 + 2x)(8 + 2x) = 168
80 + 20x + 16x + 4x² = 168
4x² + 36x = 88
because for the whole length you need to add x twice (left and right). the same for the width (top and bottom).
I think it whether 90 or 180 is there multiple choices?
2x - 24 = x - 2
2x - x = -2 + 24
x = 22
BC = x = 22
Answer:
y = 52 - 8x
Step-by-step explanation:
Add both axisis together, nd divide
Hope this helped, and please mark as Brainliest <3
Y=20x+50
Y is the total cost and x is the number of hours
