Micah was asked to add the following expressions:
First, he combined like terms in the numerator and kept the common denominator
First step is correct. He added the like terms in the numerator, because the denominators are same.
So he got , 
In the next step, he cannot cancel out x^2 from the top and bottom . Because x-4 and 3x+2 are added with x^2
If we have x^2 is multiplied with other terms at the top and bottom , then we can cancel out x^2.
So Micah added the expression incorrectly. Final answer is not correct.
Answer:
(0, 7]
Step-by-step explanation:
Let's call the width W and the length L. The length is 18 feet more than the width, so:
L = W + 18
The area can be no more than 175, so:
A ≤ 175
LW ≤ 175
Since L = W + 18:
(W + 18) W ≤ 175
W² + 18W ≤ 175
W² + 18W - 175 ≤ 0
(W - 7) (W + 25) ≤ 0
-25 ≤ W ≤ 7
However, the width of the table can't be nonpositive, so:
0 < W ≤ 7
Or in interval notation, (0, 7].
Step-by-step explanation:
4h+6h2+1−(5h2−8h4+6)
=4h+6h2+1+−1(5h2−8h4+6)
=4h+6h2+1+−1(5h2)+−1(−8h4)+(−1)(6)
=4h+6h2+1+−5h2+8h4+−6
=4h+6h2+1+−5h2+8h4+−6
=(8h4)+(6h2+−5h2)+(4h)+(1+−6)
=8h4+h2+4h+−5 <- Answer
