18.) 9x^{5} + 27x^{4}

19.) -12y^{3} - 12y^{2} - 12y - 12

20.) x^{2} + 9x + 20

21.) 4x^{2} - 5x - 6

22.) m^{6} +2m^{5} + m^{4}

23.) 2 m ^{7}+ 3 m ^{6} + 2 m ^{4} + 10 m ^{3} + 15 m^{ 2} + 10

Step-by-step explanation:

17.) Distribute 2x^{2} to all of the terms in the parenthesis.

18.) Combine Like Terms (x and 9x^{4}\\) Multiply all other terms by 9x^{4}

19.) Multiply terms within the separate parenthesis together

20.) Use FOIL and expand the polynomial

21.) Use FOIL and expand the polynomial

22.) Combine like terms and multiply the contents of the parenthesis by the exponent

23.) Expand  ( m^{ 4} + 5 ) ( 2 m^{ 3} + 3 m ^{2} + 2 )  by multiplying each term in the first expression by each term in the second expression.

C. If one cubic foot contains about 7.5 gallons, how many gallons of water are in the pool? (3 points) I Water: gallons 3. A rec
Dominik [7]

Answer:

<u>One Rectangular Pan</u>

Step-by-step explanation:

Part C cannot be answered since the dimensions of the pool are not given.  Please check the question.

The cake pans may be compared by calculating the volume of each shape:

Rectangular pan:  Volume = Length x Width x Height

  Volume Rectangle = (13")*(9")*(2") = <u>234 in^3</u>

Round pan:  Volume = \pi r^{2} h

  Volume Round = (3.14)*(4")^2(2") = 100.5 in^3

Two round pans will hold 2*(100.5 in^3) or 201 in^3 of batter

One rectangular pan holds 234 in^3.

Go with the rectangular pan if you want more cake.

Answer and how to solve this
nata0808 [166]

Step-by-step explanation:

When it says x = something, that basically means to replace the x with whatever it says x equals.

x = 0. Equation /. 3 x 0 = 0 + 1 = 1. Y = 1

x = -1. Equation/. 3 x -1 = -3 + 1 = -2. Y = -2

x = 2. Equation/. 3 x 2 = 6 + 1 = 7. Y = 7

Hope this helps!! (:

umka2103 [35]

Answer:

\frac{19}{18,750,000}=0.0000010133333333

Step-by-step explanation:

We have been given that in a recent​ year, 304 of the approximately​ 300,000,000 people in the United States were struck by lightning.

\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Number of possible outcomes}}

\text{P( A randomly selected person in the United States will be struck by lightning this year)}=\frac{304}{300,000,000}

\text{P( A randomly selected person in the United States will be struck by lightning this year)}=\frac{19}{18,750,000}

\text{P( A randomly selected person in the United States will be struck by lightning this year)}=0.0000010133333333

Therefore, the probability that a randomly selected person in the United States will be struck by lightning this year is \frac{19}{18,750,000}=0.0000010133333333.
