Answer:

n(E) = 6

Step-by-step explanation:

That's to say that there are 6 five-digit numbers with 7 in the first place and 8 in the last place, using the digits 2, 3, 4, 7 and 8. Therefore n(E) = 6.

At the store I can buy a 2 pack of shirts for $22.78 or a 6 pack of shirts for $67.80. Which is the better deal?
mina [271]

Answer: A 6 pack of shirts for $67.80 is the better deal than the other one.

Step-by-step explanation: Is that one because you need to divide each of the prices to the number of shirts. First, lets start of with 22.78/2, 22.78 divided by the 2 pack of shirts is a quotient of $11.39.

Next lets do $67.80 / 6, So 67.80 divided by 6 equals $11.30. Meanwhile, 11.30 < 11.39 because of the sale. So that's why the 6 pack of shirts for $67.80 is the better deal.

Factor the expression below. x2 - 6x + 9 A. 3(x2 - 2x + 3) B. (x - 3)(x + 3) C. (x + 3)(x + 3) D. (x - 3)(x - 3)
beks73 [17]

For this case we must factor the following quadratic expression:

x ^ 2-6x + 9

To factor, we must find two numbers that when multiplied give as result +9 and when added or subtracted give as result -6.

These numbers are:

-3 and -3

-3-3 = -6\\-3 * (- 3) = + 9

So, we have:

(x-3) (x-3)
