Answer:
The first answer is 3) 9(3r-4) and 27r-36
The second answer is 2) Y squared - 36/6
The third answer is 1) 300
Explanation:
First answer :
Equivalent expressions are expressions that work the same even though they look different.
9(3r-4) is equal to 27r-36.
9 x 3r = 27r
9 x 4 = 36
27r-36
Second answer :
"The square of y decreased by quotient of 36 and 6" Explains the answer which is Y squared - 36/6
Third answer :
The formula you want to follow is: 2(LW+WH+HL)
2(LW+WH+HL) = 2(12x9+9x2+2x12)
2(12x9+9x2+2x12) = 300
