Answer:
The width of the rectangle is 5 inches.
Step-by-step explanation:
Perimeter of a rectangle: 2L+2W where L=length and W=width
P=56
56=2(4W+3)+2W
56=8W+6+2W
56=8W+2W+6
56=10W+6
56-6=10W
50=10W
W=50/10=5
W=5
L=4W+3=4(5)+3=20+3=23
Answer:
The answer is (x+y)^3
Step-by-step explanation:
using the division/subtraction law of indices
In indices division is equal to subtraction on powers
(x+y)^5 ÷ (x+y)^2
=(x+y)^5-2
=(x+y)^3
3, 7×3=21+5=26, there is your answer
