A-12 10
=
4 3

i just moved to america this summer an i am learning algebra 2. i got the answer but i don’t know how to work out this problem. pls me and show work.

a = 76/3

Step-by-step explanation:

I completely understand your frustration. Algebra 2 is also painful for me this year.

1. Since these equations are equal to each other, you can cross multiply them and set those equal to each other: (a -12) • 3 = 4 • 10.

2. Solve: (a-12) • 3 = 4•10

3a-36 = 40

3a=76

a= 76/3.

(Is this supposed to be a whole number?)

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
