Two students write the following expressions to answer an exercise: 7 + 4(5 – 3)2 + and 8 + (5 – 3)24 + 7

a. Simplify the two expressions. List each step you use.

b. Explain the similarities in the steps.

C. Make up another expression that uses the same numbers and operations, but
has a different value. Then simplify the expression, listing each step.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

c - they will have the same distribution

this is the only one that could make sense. : )
