15. $(-k^{3} -5k^{2} + 1) - (6k^{3}-k^{2} -2)$

Step 1: Distribute the subtraction sign to all the numbers in the second set of parentheses...

$(-k^{3} -5k^{2} + 1) - (6k^{3}-k^{2} -2)$

$-k^{3} -5k^{2} +1 - 6k^{3} +k^{2} +2$

Step 2: Combine like terms ( $k^{2}$ 's go with $k^{2}$ 's)

$-k^{3} -5k^{2} + 1 - 6k^{3}+k^{2} +2$

$-5k^{2} +k^{2}$

$-4k^{2}$

$-k^{3} -4k^{2} + 1 - 6k^{3}+2$

Step 3: Combine like terms ( $k^{3}$ 's go with $k^{3}$ 's)

$-k^{3} -4k^{2} + 1 - 6k^{3}+2$

$-k^{3} + (- 6k^{3})$

$-7k^{3}$

$-7k^{3} -4k^{2} + 1 +2$

Step 4: Combine like terms (normal numbers go with normal numbers)

$-7k^{3} -4k^{2} + 1 +2$

1 + 2

$-7k^{3} -4k^{2} + 3$

You were correct!

This year Sheila earned 8.00$ an hour. This year she earns 10.00$ an hour. What is the percent increase in the amount Sheila ear

yulyashka [42]

Answer: It is a 25% increase.

Step-by-step explanation: First lets subtract her new wage from her old wage. 10 - 8 = 2

Next, lets write an percent equation, for p = percent.

2 = p x 8

Basically, we are saying that her new wage will be what percent of her old wage.

Next,

2/8 = p

0.25 = p

Now, multiply 0.25 by 100 to get a percent

0.25 x 100 = 25

So her new wage is a 25% increase from her old wage.
