Answer the length of a rectangle is 4 centimeters (cm) less than three times the width. the perimeter is 64 cm. find the width and length. ( hint: perimeter = 21 + 2w)

L=3w-4

Perimeter = 64

64=2L+2w

Plug in L that we solved above into this equation:

64=2(3w-4)+2w

64=6w-8+2w

64=8w-8

72=8w

w=9

Plug W back into the equation above to solve for L

L=3w-4

L=(3)(9)-4

L=23

Check the answer with the perimeter formula:

P=2L+2w

P=2(23)+2(9)

P=46+18

P=64

step-by-step explanation:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
