Answer:

Option 2 is correct that is $\frac{x+2}{x+9}$ and $x\neq-9$ and $x\neq-12$

Step-by-step explanation:

We have been given with the expression $\frac{x^2-10x-24}{x^2-3x-108}$

We will simplify the given expression by factorisation we will get $\frac{x^2-12x+2x-24}{x^2-12x+9x-108}$

Taking x as common from first two terms in numerator and 2 from last two terms in numerator

Similarly, take x common from first two terms and 9 from last two terms in denominator we will get

$\frac{x(x-12)+2(x-12)}{x(x-12)+9(x-12)}$

After arranging the terms we will get $\frac{(x+2)(x-12)}{(x+9)(x-12)}$

Taking out the common factor which is (x-12) from numerator and denominator it will get cancelled we will get

$\frac{(x+2)}{(x+9)}$

Hence, Option 2 is correct that is $\frac{x+2}{x+9}$ and $x\neq-9$ and $x\neq-12$

Four students are running for class president: liz, sam, sue, and tom. the probabilities of sam, sue, and tom winning are 7⁄25 ,

Natali5045456 [20]

First, we need to convert all the fractions to have the same denominator. 10 and 25 are both multiples of 100, so 100 would be appropriate.

Sam has a 7/25 chance. Because we want ?/100, something needs to change. To get from 25 to 100, you need to times 25 by 4, right? So, do the same with the 7.
7 x 4 = 28. Therefore Sam has a 28/100 chance.

Sue has 3/10. Using the same method, we can see that 3 needs to be multiplied by 10 (because 10 times 10 = 100). So Sue has a 30/100 chance.

Tom is already in the fraction we like, so just keep this as 21/100.

Now, add 28/100, 30/100 and 21/100 to get 79/100.

Because won of them will get the role of class president, we know that the probability adds to 1. To get a full probability (100/100, or 1), what needs to be added to 79/100?

Another way of going about this is 100/100-79/100. The answer is 21/100

The probability of Liz winning is 21/100.

Let me know if this is still unclear, I would be more than happy to explain in more detail if necessary :)

F(x)•g(x)=
2(2x+1)=
4x+2
4(0)+2= 2

f(x)•g(x)=
2(2x+1)=
4x+2=
4(2)+2= 10
