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
