Y=7 is linear
y=3x^2+1/2x-x^3+1 is neither
y=2x+5x^2-1 is quadratic
y=x/(x-1) is neither
y=(x^2+8x-20)/4 is quadratic
y=(x+5)(x-4) is quadratic
I would think $<span>14,301. If is is a shared salary then just divide by two since there are two people.</span>
Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.
Answer:
The length is 72 feet.
Step-by-step explanation:
<em>Equations</em>
2L+2W=192
L=3W
<em>Solving/Substitution</em>
2(3W)+2W=192
8W=192
W=192/8=24
L=24*3=72
The length is 72 feet.
The width is 24 feet.

Answer:</h3><h2>
x + y = -4.125</h2><h3>
Step-by-step explanation:</h3>
When you have a problem with wanting the answer to be negative, you must Add the 2 negative numbers.
-11/8 = - 1 3/8, 11/4 - 2 3/4.
You should take off the negatives for this problem, and just add fractions as usual.
We need common denominators, which is 8.
Our problem is:
1 3/8 + 2 6/8.
We add, 3 + 6 = 9 / 8.
1 1/8.
2 + 1 = 3 + 1 1/8 = 4.125.
Then, we put the negative sign.
Therefore x + y is correct since the value is negative, -4.125.
Best of Luck to you.
