Answer:
(2•5y to the 7th power)
Step-by-step explanation:
Step 1: (2y to the 4th power • 5) • y to the 3rd power
Step 2: (2•5y to the 4th power) • y to the 3rd power
Step 3: 3.1 y to the 4th power multiplied by y to the 3rd power = y to the (4 + 3) power = y to the 7th power
Final answer: (2•5y to the 7th power)

Answer:
The answer to your question is below
Step-by-step explanation:
Equation 1
$sweatshirt = 2 pair of shorts
<u> w = 2h</u>
Equation 2
$t-shirt = $pair of shorts - $4
<u> t = h - 4</u>
Equation 3
Total cost = 3 sweatshirts + 2 pairs of shorts + 5 t-shirts
<u>Total cost = 3w + 2h + 5t = 136 </u>
We are technically FOILing this out... with a power of 3.
(x+y)(x+y)(x+y)
So we can first factor out the first two "x+y"s.

, multiplied by the last "x+y".

Coefficients are the number that comes
in front of a variable. In this case, 1 comes in front of

, 3 comes in front of

, 3 comes in front of

, and 1 comes in front of

.
Thus: 1, 3, 3, 1.
