Answer:
yes Cecilia make her first mistake in step 2
1/6 page = 1 hour
1page= 6 hours
5 pages would be 30 hours
Answer:
n ≥ -9
Step-by-step explanation:
Let n = the number
8 <em>less than</em> a number means "n – 8", but
8 <em>less</em> a number means "8 – n," so
8 – n ≤ 17 Subtract 8 from each side
-n ≤ 9 Multiply each side by -1
n ≥ -9
<em>Note</em>: When we multiply by a negative number, we must reverse the inequality.
<em>Check:</em>
Try n = -8.
8 – (-8) ≤ 17
8 + 8 ≤ 17
16 ≤ 17
<em>True</em>.
Answer:
(x - 1)( x - 2) (x + 2) = x³ -x² -4x + 4.
Explanation:
1) Given equation:
3 5x x + 2
- ------- + -------- = ---------------
x + 2 x - 1 x² - 3x + 2
2) So, the denominators are x + 2, x - 1, and x² - 3x + 2
3) The LCD is the product of the common and non common factors raised to the greatest power.
4) x + 2, and x - 1 are already prime factors
5) Factor x² - 3x + 2
x² - 3x + 2 = (x - 2)(x - 1)
6) Then, the factors are x + 2, x - 1, and x - 2, and the LCD is the product of them:
(x - 1)( x - 2) (x + 2)
7) If you expand the products (distributive property) you get:
x³ -x² -4x + 4.
The answer may be 36 but I am not very sure
