8. the length of vicki's garden is 4 meters greater than 3 times the width. the perimeter of her
garden is 72 meters. formula: p = 2l + 2w or p = 2(l + w)
a) which of the following system of equations could be used to represent the length and width
of the rectangle? circle the correct choice.
a. l= 3w + 4
2l + 2w = 72
b. w = 3l + 4
2[l+w) = 72
c. l= 3+ 4w
2l + 2w = 72
d. l = 4w-3
2(l + w) = 72
b) now solve the system using either elimination or substitution.

A

Step-by-step explanation:

The length is 3 times longer than the width, plus 4. You add the 4 to the 3w. Since it’s a rectangle and has 4 sides that are parallel and are equal it’s 2L plus 2W.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
