Step-by-step explanation:
Answer:
length = 22
width = 13
Step-by-step explanation:
Perimeter of a rectangle is given by the formula
P =2(l+w)
we know the length is x
width is x-9
P =70
Substituting this into the equation
70 = 2(x+x-9)
Combining like terms
70=2(2x-9)
Distributing the 2
70 = 4x-18
Adding 18 to each side
70+18 = 4x-18+18
88 = 4x
Divide by 4
88/4 = 4x/4
22= x
we know the length is x
length = 22
width is x-9
width = 22-9= 13
Answer: Check explanation
Step-by-step explanation: -g-6, 9d+3, -12y+20, 14n-29, -2c, x+21/2
Well, all we have to do is add, so:
6 + (-47) =
6 - 47 =
-41
