Answer: $\boxed{\bold{-14x+8}}$

<><><><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><><><>

[ Step One ] Remove Parenthesis: (a) = a

$\bold{x^2-9x+2+4x^2-5x+1-\left(5x^2-5\right)}$

[ Step Two ] Simplify $\bold{-\left(5x^2-5\right)}$

$\bold{-5x^2+5}$

[ Step Three ] Rewrite Equation

$\bold{x^2-9x+2+4x^2-5x+1-5x^2+5}$

[ Step Four ] Simplify $\bold{x^2-9x+2+4x^2-5x+1-5x^2+5}$

$\bold{-14x+8}$

Which ratios are equivalent to 10:16? Check all that apply. 30 to 48 25:35 StartFraction 40 Over 64 EndFraction 8:32 5 to 15

schepotkina [342]

Answer:

30 to 48, 40/64

Step-by-step explanation:

Which ratios are equivalent to 10:16, and they gave us 30 to 48, 25:35, 40/64, 8/32 and 5 to 15.

For 30 to 48, we can mulitply the 10:16 by 3 to give us 30:48, so it is equal.

For 25:35, we simplify it to 5:7, while 10:16 is 5:8, so they are not equal.

For 40/64, we can take 10:16 and multiply them by 4, getting the same number. Therefore, it is equal.

For 8/32, we can simplify it down to 1/4, while 10:16 simplifies down to 5:8, it is not equal.

Lastly, for 5 to 15, w can simplify that to 1/3, and get 5:8 for 10:16, so it won't be equal.

What is the probability that if 13 letters are typed, no letters are repeated?

faltersainse [42]

If there are 13 letters typed, the probability that no letters will be repeated can be found to be 1.05 x 10⁻²⁰

<h3>How to find the probability no letters are repeated?</h3>

First, find the number of possibilities of 13 letters from 26 letters in the alphabet as:

= 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26

= 6.156 x 10³⁶ possibilities

If the numbers are not to be repeated then the possibilities are:

= 26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 16 x 15 x 14

= 64764752532480000 possibilities

The probability that no letters are repeated is:

= 64764752532480000 / 6.156 x 10³⁶

= 0.0000000000000000000105

= 1.05 x 10⁻²⁰
