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
Step-by-step explanation:
angles on a straight line

I don't know this because it's so confused sorry boy or girl I'm so sorry
D. You can find a perpendicular line by finding the inverse equations (-(1/)2 x+3
Answer: x = 12
Step-by-step explanation:
= 
cross multiply
4x = 6 × 8
4x = 48
divide through by 4
x = 12
