Arectangle's length is 3 feet longer than its width. its perimeter is 62 feet

Hi!

l + l + w + w = 62

w + 3 + w + 3 + w + w = 62

4w + 6 = 62

4w + 6 - 6 = 62 - 6

4w = 56

4w/4 = 56/4

w = 14

14 + 3 = 17

Hope this helps! :)

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
