Given the expression 42 + 96, which value of a could not be used to create an equivalent expression in the form a(b + c) where a is a common factor of 42 and 96? a) 2 b) 3 c) 6 d) 7

  D)  7

Step-by-step explanation:

2, 3, and 6 are common factors of 42 and 96. 7 is not. If a, b, and c are to be integers, the value of "a" must be a common factor of 42 and 96. It cannot be 7.

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

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
