Answer:
The length is 22.5 and the width is 19.5
Step-by-step explanation:
2L + 2W = P
\/
2L + 2W = 84
\/
W + 3 + W + 3 + W + W= 84
\/
4W + 6 = 84
\/
4W = 78
\/
W = 19.5 L = 19.5 + 3 = 22.5
I hope this helps, have a nice day! :D
Answer:
y = 3
Step-by-step explanation:
2x-3y = -5 --------- (1)
y = 2+x ------- (2)
substitute (2) into (1)
2x-3y = -5
2x-3( 2+x ) = -5
2x-6-x = -5
2x-x = -5+6
x = 1
substitute x = 1 into (2)
y = 2+x
y = 2+1
y = 3
