I could explain it, but you have to ask me, other than that the answer is 5(x+7)(9x-4).
Answer:
<em>There is no y value so I think you mean to solve for x</em>
<em>Here's how we do it!: </em>
<em>1/2(x-12) = 4</em>
<em>Add 12...</em>
<em>1/2(x) = 4</em>
<em>Divide by 1/2...</em>
<em>x = 8!</em>
<em>x equals 8 in this case</em>
False. A CONCAVE polygon looks like it collapsed or has indentations.
Remark
The easy way to do this is to change 5/8 to a decimal and worr y about changing it back to a fraction if you need to.
15 5/8 = 15.625 The easy way to find 5/8 is to use your calculator. 5 ÷ 8 = on most calculators.
You want 12 of these
1 leg is 15.625 inches long.
12 legs = x
1/12 = 15.625 / x Cross multiply
x = 12 * 15.625
x = 187.5 inches
Just how many feet is that? Divide by 12 to get the number of feet 187.5 / 12 =
15.625 feet.
Usually 2 by 4s are 8 or 12 feet long. For 8 feet you will need 2 of them and for 12 feet unfortunately you will need two as well.
