The dimensions of a rectangle are 3x - 4 and 5x - 11. Which formula can be used to find the perimeter p of the rectangle?
2 answers:
Answer: 16x - 30
Step-by-step explanation:
Determine values of L and W
We know that the perimeter can be found by the equation p = 2L + 2W where L is the length and W is the width
L = 3x-4
W = 5x-11
Plug in the values of L and W into the equation and solve
p = 2L + 2W
p = 2(3x - 4) + 2(5x - 11)
p = 6x - 8 + 10x - 22
p = 16x - 30
Answer:
(16x - 30) units
Step-by-step explanation:
Perimeter = 2[length + width]
= 2[3x-4 + 5x-11]
= 2[8x - 15]
= 16x - 30

All you need to do is divide 32 by 4.
32/4= 8
So, 3*8= 24 (that is 3/4 of the cupcakes)
32-24= 8
8 is the answer.
