Answer:
11 17/21
Step-by-step explanation:
Answer:
Length = 21
Width = 16
Step-by-step explanation:
We know that the formula for perimeter is:
P=2W+2L
And we also know that:
L=W+5
So then we put all that we know in the formula:
74=2W+2(W+5)
Now we expand the brackets and do some algebra:
74=4W+10 (-10)
64=4W (÷4)
16=W
Now that we know the width we can pop that into the length equation:
L=16+5
L=21
The answer is 17/5. First you multiply 5*3=15 then you add 2 which your answer is 17/5.
Answer:
The answer is B(65)
Step-by-step explanation:
you just do 180 - JCB = 65
so you do 180-65=115
hope this helps
