Question

The length of a rectangle is five more than four times the width, and the perimeter
is 40.

Answer 1

if you call the length L and the width W

you must translate
length of a rectangle is five more than four times the width
into an equation

length of a rectangle replace with L

L is five more than four times the width

is replace with =
L = five more than four times the width
five and four, replace with numbers
L = 5 more than 4 times the width
the width replace with W
L = 5 more than 4 times W

times replace with * (or just leave it out)
L = 5 more than 4W

what do you replace "more than" with ?

Answer 2

so what is the equation
