Answer:

A=252

Step-by-step explanation:

B=28mm

P=74mm

we know the two sides of B= 28

28+28= 56

the perimeter is every added up P= 74

so we must minus 56-74 = 18

meaning side A= 18 then we divide it by 2 which is 9

to check... 9+ 28+9+28 = 74 same answer if 18+56= 74

Formula for Area = Lxw meaning 9x28

9x28 = 252

I need help on this question for math
Ganezh [65]

Answer:

y = -12

Step-by-step explanation:

any equation with only an x or y value present will either be a vertical or horizontal line. Because the y axis is vertical, a line that is present on y=-12 will sit on y=-12 forever, and therefore be a horizontal line
