You have to <em>FOIL</em> (multiply the first, then outer, then inner, then last)
(x-2)(x+4)
First: multiply x by x to get x².
Outer: multiply x by 4 to get 4x.
Inner: multiply -2 by x to get -2x.
Last: multiply -2 by 4 to get -8.
This gives you:
x² + 4x - 2x - 8
Combine like terms to get your final answer:
x² + 2x - 8

The perimeter of second plot is 180 feet
<em><u>Solution:</u></em>
Given that,
The second parking lot is being designed so that its perimeter is 3/4 of perimeter of the first parking lot
<h3><u>Find the perimeter of first plot:</u></h3>
Perimeter = 2(length + width)
From given figure in question,
length = 40 feet
width = 80 feet
Therefore,
Perimeter = 2(40 + 80)
Perimeter = 2(120) = 240
Thus, we got,
Perimeter of first parking plot = 240 feet
Also, given that,
Thus perimeter of second plot is 180 feet
9/8..... 9 friends divide 8 bags of apples evenly
Answer:
1/6a-1/6
Step-by-step explanation:
-2/3 transferred into 6th's is -4/6. You combine like terms, -4/6a+5/6a=1/6a
Then since -1/6 doesn't have a like term, it stays the same.
<span>The simplified form of the following expression: (8r to the power of -5) minus 3, is (8r^-5) - 3.
Your final answer is (8r^-5) - 3.</span>
