A rectangle has a length 3 times the width. What is the perimeter in terms of x?
1 answer:
Answer:
Perimeter is equal to all four sides added together.
Length = 3W; L=3W
So
P = 2(W) + 2(L) substitute the equation for length above you get
P = 2(W) + 2(3W) and combine
P = 2W + 6W = 8W; put in what the perimeter is and solve for W
66 = 8W, so W = 8.25
W = 8.25, L = 24.75

The answer is I believe b=70
Answer:
234
Step-by-step explanation:
The square root of -3 is 1.73205081
since there are 180 degrees in a triangle so :
65+72+y=180 add like terms
137 + y=180 now subtract 137
y= 180-137
y=43 degrees
