Select the two expressions that do NOT equal the number of square pieces
that make the frame below.

A.(9 5) - (8 x 4)
B.(9 5) - (7 ~ 3)
C. 9 + 3 + 9 + 3
D. 9 + 5 + 9 + 5
E.2(8 + 4)

answer: 1, 3 and 5 are correct

step-by-step explanation:

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
