12, 24, and 60.

Step-by-step explanation:

It says multiples. Not factors, so it can't be 1 or 2. Neither of the numbers can make the number 10. 4 can make 40, but 6 can't.

Simplify the expression -4x2(3x − 7).

11111nata11111 [884]

-4*2(3x-7)
-8(3x-7)
8 times 4 is 24 so it would be negative 24
so 3 times 16.3=48.9 then you add 7 which rounds it off it 56
so x is 16.3 thats how you get this expession

Given that f(x) = x2 – 5x – 14 and g(x) = x – 7, find (f +g)(x) and

Angelina_Jolie [31]

Answer:

$(f+g)(x)=x^2-4x-21$

Step-by-step explanation:

We are given:

$f(x)=x^2-5x-14\text{ and } g(x)=x-7$

And we want to find:

$(f+g)(x)$

This is equivalent to:

$=f(x)+g(x)$

Therefore, by substitution:

$=(x^2-5x-14)+(x-7)$

Rearranging gives:

$=(x^2)+(-5x+x)+(-14-7)$

Combine like terms:

$=x^2-4x-21$
