Answer:
=2m³−m²u+m²+3m+2
Step-by-step explanation:
m²+2mm²−um²+3m+2
= m²+2m³+−m²u+3m+2
= 2m³−m²u+m²+3m+2
Answer:
15 packages
Step-by-step explanation:
Set up a proportion, where x is the number of packages she can wrap with 2.5 rolls of wrapping paper:
= 
Cross multiply and solve for x:

Part a: subtract 48-30=18
Part b: i found it by subtracting 48 -30 because it says left over
Answer: b.) 40
Given that:
f(x) = 5 × 2ˣ
To find f(3), simplify insert [x = 3] in the given equation:
f(3) = 5 × 2³
f(3) = 5 × 2 × 2 × 2
f(3) = 40
