Hi Jessica,
<span>Remember PEMDAS (Parenthesis, Exponents, Multiplication & Division, Addition & Subtraction).
√3 x 66.15/4.41 {Exponents/Cube & Square Roots First}
1.73 x 66.15 ÷ 4.41 {Multiplication}
114.4395 ÷ 4.41 {Division}
25.95 {Final Answer}
Cheers,

Answer:
D= 37
C= 53
x+x-16=90

2x=106
/2 /2
x=53
60 because all the negatives would cancel out so all you have to do is multiply the numbers
