Makayla is taking a math course and is working with the perimeter of rectangles. She knows the perimeter and length of her rectangle but wants to solve for the width. Rearrange the following equation for W, where P is the perimeter, L is the length, and W is the width of the rectangle. P = 2L + 2W

W = 2P − 2L
W equals P over 2 minus 2 times L
W equals the quantity P minus 2 times L all over 2
W = 2P + 2L

W equals the quantity P minus 2 times L all over 2

Step-by-step explanation:

P = 2L + 2W

Subtract 2L from both the sides,

2W = P - 2L

Divide by 2 on both the sides,

W = (P-2L) / 2

it’s supposed to be -4+45=41

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
