2 Do Marc buys three magazines for $7.50 at a school fundraiser. If all magizines in the fundraiser cost the same, what is the constant of proportionality in this situation? A: 2
B: 2.5
C: 3
D: 7.5​

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

step-by-step explanation:

hi there!

the answer will be d: 2

the answer is 99.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
