When you foil it out you should get: 2x^5-2x^3-12x. When you factor it out completely you get: 2x(x^2-3)(x^2+2)

Answer:

1. 2 eggs 2. 53 mph 3. $8 per hour 4. 1 \frac{3}{4} gal per hour

Step-by-step explanation:

1. There are 4 eggs used in 2 batches. For one batch, you divide 4 eggs by 2 batches to get 2 eggs for each batch.

2. There are 265 miles in total, so to get the average speed each hour, you divide the total by 5 hours to get 53 miles per hour.

3. In 7 hours, he got $56. Divide 56 by 7 to get the pay each hour, which would be $8 per hour.

4. In a half hour, the swimming pool has leaked a certain amount of water. Double that to get how many gallons per hour. \frac{7}{8} * 2= 1 \frac{3}{4} gallons per hour.

Which expression is equivalent to the radical expression shown below when it is simplified?
babymother [125]

Answer:

\sqrt{\frac{3}{64} } in simplified form is \frac{\sqrt{3}}{8}

Step-by-step explanation:

We need to solve the expression

\sqrt{\frac{3}{64} }

We know that \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}

and 64 = 8*8

Solving we get

=\frac{\sqrt{3}}{\sqrt{64}}\\=\frac{\sqrt{3}}{\sqrt{8*8}}\\=\frac{\sqrt{3}}{\sqrt{8^2}}\\=\frac{\sqrt{3}}{8}

So \sqrt{\frac{3}{64} } in simplified form is \frac{\sqrt{3}}{8}

You roll two fair dice, a green one and a red one.
olga_2 [115]

Answer:

(a) yes

(b) 1/36

(c) 1/36

(d) 1/18

Step-by-step explanation:

(a) yes they are independent as the outcome of one does not affect the outcome of the other.

(b) As the dice are fair, each possible number (1 through 6) has the same probability of being rolled.

P(1 on green die) = 1/6

P(2 on red die) = 1/6

Therefore, P(1 on green die) AND P(2 on red die) = 1/6 × 1/6 = 1/36

(c) Again, as the dice are fair, each possible number (1 through 6) has the same probability of being rolled.

P(2 on green die) = 1/6

P(1 on red die) = 1/6

Therefore, P(2 on green die) AND P(1 on red die) = 1/6 × 1/6 = 1/36

(d) p[(1 on green die and 2 on red die) OR (2 on green die and 1 on red die)

= 1/36 + 1/36

= 2/36

= 1/18
