If that is a multiplication sign then the answer is 12. But if that is 5x^4 then the answer is -(5x^4-32)
Well evaluate means solve . so you just substitute the -18 in place of x you'll get -18-10/ 4

Answer:
a
Step-by-step explanation:
(2x + 3y)²
= (2x + 3y)(2x + 3y)
Each term in the second factor is multiplied by each term in the first factor
2x(2x + 3y) + 3y(2x + 3y) ← distribute parenthesis
= 4x² + 6xy + 6xy + 9y² ← collect like terms
= 4x² + 12xy + 9y² → a
