Answer:
4x2y2−12y
Step-by-step explanation:
Write the problem as a mathematical expression. ( x y 2 x − 3 y ) ⋅ 4 Multiply x by x by adding the exponents. ( x 2 y 2 − 3 y ) ⋅ 4 Simplify by multiplying through. 4 ⋅ ( x 2 y 2 ) − 12 y Remove parentheses. 4 x 2 y 2 − 12 y
2.95 per movie....39.95 per month
the yearly cost would be :
39.95(12) + 2.95x....and if u need it simplified more, it would be :
479.40 + 2.95x
