Say the width is W and the length is L
L=3W (and of course W=W)
Now you use the perimeter formula P=2L+2W
80=2(3W) + 2W)
80=6W+2W
80=8W Divide both sides by 8
W=10
Now that you know the width, substitute it back into L=3W to find the length
L=3(10)
L=30
The dimensions are length: 30 cm and width: 10 cm
Answer:
Step-by-step explanation:
4 cm to 25 miles = 20 cm to x miles
4 / 25 = 20 / x
cross multiply
4x = (25)(20)
4x = 500
x = 500/4
x = 125 miles <=====
Answer:
4
Step-by-step explanation:
a+b=cdfg = 4
big brain.
The answer of g(x) =|x+2|-1 is X1 =-3, X2=-1
You don't ave enough information I can't answer that question
