The perimeter of a rectangular garden is 276 feet. If the width of the garden is 57 feet, what is its length?

81

Step-by-step explanation:

57(2)=114 (for the 2 widths of the rectangle)

276-114=162 (the given perimeter minus the 2 widths)

162/2 (since there are 2 lengths)

=81

hope that helps:)

most likely linear (proportionate)

step-by-step explanation:

as time increases heart rate increases

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
