What are the excluded values of x for x^2-3x-28/x^2-2x-35

x=-5, 7 are the excluded values

Step-by-step explanation:

Excluded values are the values that makes the denominator 0

To find excluded values we set the denominator =0  and solve for x

Factor x^2 - 2x - 35

(x-7)(x+5) =0

We set each factor =0  and solve for x

x-7 =0  so x= 7

x+5 =0 so x= -5

x=7, x=-5 makes the denominator 0

So x=7 , x=-5 are the excluded values

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
