Which expressions have a value of 33

A. 15 + (8*3-6)

B. (30+6) / 6+3*2^2

C. 40-[5 * (3+1) + 8]

D.[ (3+5) * 2-5]*3

Let's look through the options one by one:

A. 15 + (8*3-6)

inside the parentheses, we multiply first

15 + (24-6)

now simplify the rest of the parentheses

15+18

33

so answer "A'' equals 33

B. (30+6) / 6+3*2^2

we simplify the inside of the parentheses

36/6+3*2^2

we simplify the exponent

36/6+3*4

6+12

18

So NO, answer "B" is not correct

C. 40-[5 * (3+1) + 8]

all the way on the inside of the parentheses,

40-[5*4+8]

multiplying comes before adding, so

40-[20+8]

inside the brackets,

40-28

12

So answer "C" is also incorrect

D. [ (3+5) * 2-5]*3

inside the parentheses

[8*2-5]*3

multiplying before subtracting

[16-5]*3

11*3

33

So the only answers that equal 33 are answer "A" and answer "D" equal 33
