Which equation is true if the perimeter of the rectangle is 60?
X + 5
3x - 2

X+5= 3x-2
(x+5)+(3x-2) = 60
2(x+5)+2(3x-2) = 60
O 2(3x-2)-2(x+5) = 60

2(x+5)+2(3x-2) = 60

because rectangle have 2 equal sides, and 2 other quals side, u just times them with 2, and sum them together? does this make sense? hope the picture explains :/

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

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.
