So first remember the order of operations. Parentheses, exponents, multiply, divide, addition, subtraction.
So we have the following problem.
-(3*2)2+4*3-2
Multiply the three and two inside the parentheses first.
-6*2+4*3-2
Next multiply any numbers that need multiplied.
-12+12-2
Next add and subtract from left to right to get an answer of...
-2
Hope this helps!

Answer:
Step-by-step explanation:
The answer A on 2021
Number of dimes: x
Number of quarters: x + 3
Answer:
B ) 0.10 x + 0.25 ( x + 3 ) = $1.80
Also we can solve this equation:
0.10 x + 0.25 x + 0.75 = 1.80
0.35 x = 1.80 - 0.75
0.35 x = 1.05
x = 1.05 : 0.35
x = 3, x + 3 = 6
He has 6 quarters and 3 dimes.
( 6 * 0.25 + 3 * 0.10 = 1.50 + 0.30 = $1.80 - correct)
