Answer: 2a+ay+2b+by
Step-by-step explanation:
(a+b)(2+y)
=(a+b)(2+y)
=(a)(2)+(a)(y)+(b)(2)+(b)(y)
=2a+ay+2b+by
=ay+by+2a+2b
Answer:
(A) 112 miles
Step-by-step explanation:
The plane flies 48 miles in 12 minutes. First, find out the amount of miles flown in 1 minute, by simplifying the fraction:
(48 miles)/(12 minutes) = (4 miles)/(1 minute)
The plane flies 4 miles every minute.
Now solve for the amount of area that plane covers in 28 minutes. Multiply 28 with 4:
4 x 28 = 112
(A) 112 miles is your answer.

8.76×10^6 is 10^4 times as big as 8.76×10^2
Answer:
64
Step-by-step explanation:
p=6
(6+2)= 8
8x8= 64
48:
48/2 = 24
24/2 = 12
12/2 = 6
6/2 = 3
We can not divide by 2, but we can divide by 3:
3/3 = 1
That's as far as we go. So I divided by 2 four times and once by 3:
Therefore:
48 = 2 * 2 * 2 * 2 * 3
Now we take 72
72 / 2 = 36
36 / 2 = 18
18 / 2 = 9
Nine is not divisible by 2, but it is by 3, so:
9 / 3 = 3
3 / 3 = 1
That's as far as we can go.
I divided by 2 three times and by 3 two times. Therefore
72 = 2 * 2 * 2 * 3 * 3
So, taking the bigger picture:
<span><span>4872</span>=<span><span>2∗2∗2∗2∗3</span><span>2∗2∗2∗3∗3</span></span></span>
Now three two's cancel out and one three cancels out and we get
<span>2\3
answer=2\3</span>
