40/5 = 8 minutes per mile
120 minutes / 8 minutes per mile = 15 miles total
he will be able to run 15 miles in 120 minutes
Answer:
d. 3x³ and 2x³
Step-by-step explanation:
In standard form, the terms of a polynomial expression are written in order of descending powers of the variable. There will be only one term for any given power of the variable.
Here, there are two terms that have x to the third power. These terms must be combined to write the expression in standard form. They are the only terms that can be combined: 3x³ + 2x³ = 5x³.
