Answer: 288
Step-by-step explanation: 72x4
Answer:
A and C are the correct answers.
Step-by-step explanation:
Monomials without a variable go after the monomials with a variable. Variables with high exponents go first. A and C both show those.
- In choice A, since 3z has a variable, it goes before 1.
- In choice C, since -5p^5 has the highest exponent it does go first.
- Then 2p^2, since it has the second highest exponent.
- Then -3p follows, with the lower exponent.
- Then 1 goes last because it has no variable and has the lowest exponent.
To do these use the new number minus the old number, all divided by the old number
(150-120)/120=
30/120=
¼.
the collection increased by 25%
