Answer: 8
Step-by-step explanation:
.32 x 25 = 8
Answer:
1st option
Step-by-step explanation:
10 + 12 ← factor out 2 ( the GCF of 10 and 12 ) from each term
= 2(5 + 6)
I don’t have much advice, but I would make yourself a schedule and a to-do list so you stay in track, and know what you’re doing each day so you can hold yourself accountable and can’t have any excuses about “not knowing about the work” because if you’re organized and get it done fast, you will be able to know about all of you work and have beTter grades since you have more time to learn the material and turn it in on time
Thanks for the points lol

Property used: 'Power of a power'
We can raise a power to a power
(x^2)4=(x⋅x)⋅(x⋅x)⋅(x⋅x)⋅(x⋅x)=x^8
This is called the power of a power property and says that to find a power of a power you just have to multiply the exponents.
Answer:
70 gallons
Step-by-step explanation:
I know there are 4 quarts in a gallon, so divide the given quarts amount by 4!
280 ÷ 4 = 70.
