Answer:

(47+37)(47-37)

Step-by-step explanation:

47^2-37^2 is a difference of two squares. a^2-b^2 = (a+b)(a-b) so this expression can be factored to (47+37)(47-37) = (84)(10) = 840

kotykmax [81]

Answer:

Altogether they sell <u>1634</u> apples.

Step-by-step explanation:

GIven:

Bob, Joe and Larry sold apples at the farmers market.

<u><em>Bob sold 86 apples. </em></u>

<u><em>Joe sold 12 times as many as Bob. </em></u>

<u><em>Larry sold half as many apples as Joe. </em></u>

Now, to find the total apples Bob, Joe and Larry they all sell together.

<u>Number of apples Bob sold</u> = 86.

<u>Number of apples Joe sold</u> = 12 times of 86.

=12\times 86\\\\=1032.

<u>Number of apples Larry sold</u> = \frac{1}{2}\ of\ 1032

=\frac{1}{2} \times 1032

=516.

Now, to get the apples they sell altogether we add the number of apples sold by Bob, by Joe and by Larry:

86+1032+516

=1634.

Therefore, altogether they sell 1634 apples.

Jason is 5 foot 11 inches tall. Amy is 63 inches tall. Who's taller and by how much 1 foot = 12 inches
jok3333 [9.3K]
Since 1 foot = 12 inches,
5 feet x 12 inches = 60 inches
Jason would be 60 inches + 11 inches tall which would = 71 inches.

71 inches is greater than 63 inches.
And 71 in -63 in= 8 in.
Therefore, Jason is taller by 8 inches
