The length of a rectangle is 3 feet more than 5 times its width. The perimeter of the rectangle is 42 feet.
1 answer:
42 = 2(W+L)
21= (W+L)
L= 3+5W)
21= W +(3+5W)
21= 3+6W
21-3=6W
18=6W
W=18/6
=3
Answer:
w = PERIMETER/2 - LENGTH
<u>w = 42/2 - (3+5w)</u>
PS. I THINK THIS IS RIGHT. NOT TOO SURE, BUT MOST LIKELY.

Step-by-step explanation:
<span>4p - 5 • (p + 6)
</span>-p - 30 = -1 • (p + 30)<span>
</span>
<span> -p - 30</span>
Pretty sure ( -2,-7) because from -1 you go over one then each y is going down 3 so -4 - 3 is -7
I think it’s 4 if the lines are going up by 2
