length of a rectangle is 6 less than 3 times its width"
L = 3W-6
"perimeter of the rectangle is 148 meters"
2L + 2W = 148
L + W = 74
(3W-6) + W = 74
4W = 80
W = 20 m
L = 3W-6 = 54 m

Answer:
the answer is x = 7
Step-by-step explanation:
1) replace the x with 7
2) 7 + 16 = 23
3) 4(7) = 28
4) 28 - 5 = 23
they're both equal as perpendicular angles should be!
