I believe the correct answer is 0
Step-by-step explanation:
To solve this question, we use an abbreviation formula called BODMAS which is:
B = Brackets
O = Of
D = Division
M = Multiplication
A = Addition
S = Subtraction
We solve each element that is available in the order of the abbreviated letter.
1. We solve the brackets:

2. We solve the second bracket:

The equation now is 
3. We now solve addition first:

4. Now we solve the subtraction:

The answer then = 0

The answer of the question is A
So see if u can factor out the trinomial.
it's factorable.
(x+3)(×-2)
so divide that factors by (×-2)
(×-2)(×+3)
---------
(×-2)
the (×-2) cancel out, leaving x+3
X=18 and y=10 because they are both 90degree angles therefore all you have to do is solve the equations: 5x=90 and 9y=90.
