Factor everything out except for ones that can no longer be factored.

\frac{y(y-2)}{(y+5)(y+2)} x (y+5)

y+5 divided y+5 is one so the answer is

\frac{y(y-2)}{y+2}

F∧-1(-2)<br> i need help solving this f to -1 power times -2
elena-14-01-66 [18.8K]

The solution is f².

<h3>How to solve for this</h3>

The question that we have here is of the form f to -1 power times -2. To have a better graphic image we can rewrite it as

f^-^1^(^-^2^)

Now we have to multiply the powers -1 and -2

Remember that in the rules of mathematics, the solution for -1 and -1 = 1

This tells us that - * - = +

Hence we would have -1 * -2

= 2

Therefore the power would be f²

<h3>How do you simplify exponents and powers?</h3>

In order to carry out the simplification of exponents what you have to do would be the multiplication of the exponents that are in the question. The base of the question remains unchanged.

For example, (2³)⁵ = 2³ˣ⁵ = 2¹⁵. For any positive number x and integers a and b: (x^a)^b = x^a^.^b

The exponents here are the numbers that are written above the base. They usually tell us how many times the base would have to be multiplied by itself to get a  solution.

Fiona wants 6 red, 3 green and 3 yellow buttons on her dress. All buttons must be placed along a straight vertical line with no
elixir [45]

The appropriate method to use in solving the given question is permutation. Then, the numbers of ways to arrange the buttons is 1320 ways.

In the given question, the order of arrangement is important, so that the number of ways that Fiona could order the buttons can be determined by permutation method.

i.e _{n}P_{r} = \frac{n!}{(n - r)!}

Red      6

Green   3

Yellow  3

Total     12

Since no two neighbouring buttons of the same colour is allowed, then 3 buttons would be arranged at a time.

Thus, n = 12 and r = 3;

_{12}P_{3} = \frac{12!}{(12 - 3)!}

      = \frac{12!}{9!}

      = \frac{12*11*10*9!}{9!}

      = 12 x 11 x 10

_{12}P_{3} = 1320

Therefore the buttons can be arranged in 1320 ways without two neighbors having the same colour.

A takeaway sells 10-inch pizzas and 12-inch pizzas.
N76 [4]

Answer:

532.52

Step-by-step explanation:

P 2(10-inch pizza)=407*3.72-358*0.49=1514.04-175.42=1339.62

P2(12-inch pizza)=169*5.26-142*0.04=888.94-5.68=883.26

P=1339.62+883.26=2222.88

2222.88-1690.36=532.52
