Answer:
Width=9.5, Length=32.5
Step-by-step explanation:
Let x be the width of the rectangle,
The length is 4 feet more than 3 times the width,
The length= 3x+4
The perimeter is
2(x)+2(3x+4)=84
2x+6x+8=84
8x=76
x=76/8
x=9.5
The Width=9.5
Length= 3(9.5)+4=32.5
Answer: 30
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
y / 4 = 39 / 30
y / 4 = 1.3
y / 4 * 4 = 1.3 * 4 (What you do to on side you also do to the other)
y = 5.2
So, your answer should be C, 5.2
