If x is a number that is 7 more than y, how do you express x as a function of y? o a. x= f(y) = 7 + x ob. x = f(y) = 7 + y o c. y = f(x) = 7x d. y = f(x) = y-7 e. y = f(x) = 7 + y

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
