2. Factors of x^2 - 5x + 6 are (x-2)(x-3) so the answer would be 2) (x-2)
4. Factors of x^2 + x - 20. First find the factors of 20. 1, 20; 2, 10, 4, 5. Then find which factors would equal "b" in the equation or in this instance "1". This would be 4 & 5. Since "c" is a negative 20, one of the factors will be a negative. So, the factors of this trinomial are (x-4)(x+5).
6. Factors of n^2 + 3n - 54. First find the factors of 54. 1, 54; 2, 27; 3, 18; 6, 9. Then find which of these factors would equal 3. This would be 6, 9. Since 54 is negative, and 3 is positive, the larger of the two factors will be the positive # and the smaller will be the negative #. So, the factors of this trinomial are (x-6)(x+9).

Comparing Leaking Pool Problem

Blababa [14]

Answer:

Pool 1 leaks faster than pool 2.

Step-by-step explanation:

Rates of change

The rate of change (ROC) is a measure that compares two quantities, usually to know how fast one variable changes in time.

We are given two rates of change for two pools that are leaking. The first one loses 2/3 gallon in 15 minutes, and the other loses 3/4 gallon in 20 minutes.

To compare them, we are required to express time in hours. Recall one hour has 60 minutes, or equivalently, one minute has 1/60 hours. Converting both times, we have:

15 minutes = 15/60 = 1/4 hours

20 minutes = 20/60 = 1/3 hours

Now compute both rates of change:

Pool 1:

$\displaystyle ROC_1=\frac{2/3}{1/4}=\frac{8}{3}\approx 2.67\ gal/h$

Pool 2:

$\displaystyle ROC_2=\frac{3/4}{1/3}=\frac{9}{4}= 2.25\ gal/h$

Comparing both ratios, it's clear pool 1 leaks faster than pool 2.

Elza [17]

Lanzetta Elem. raised 5358....round to 5,000
Lantana Mid. Sch raised 2834....round to 3,000
Atlanta High Sch. raised 4132...round to 4,000

they need 14,000...they have (5,000 + 3,000 + 4,000) = 12,000....so they will need (14,000 - 12,000) = 2,000 more....keep in mind, these are estimates...not exact answers
