Answer:

6x - 4x

Step-by-step explanation:

x^2 + 2x – 24

We need to find out the factors that replace the middle term +2x

Constant term is -24

coefficient of middle term is +2

We need to find out two factors whose product is -24 and sum is +2

6 times (-4) = -24

6 + ( -4) = 2

So 6 and -4 gives us product -24 and sum +2

the middle term +2x can be written as 6x - 4x

Let f(x) = x^2+ 5x and g(x) = 5 - x. Find f(3) + g(3)

Alchen [17]

Answer:

Step-by-step explanation:

f(x)=x^2+5x g(x)=5‒x

f(3)=3^2+5(3) g(3)=5‒3

f(3)=9+15 g(3)=2

f(3)=24

f(3)+g(3)=24+2

=26

i think it is easy to understand &i hope it helps you

Translate the sentence into an equation. Five more than the product of a number and 9 is equal to 6

kap26 [50]

The first thing we will do for this case is to define the following variable:
x = real number.
We then have the following sentence:
"Five more than the product of a number and 9 is equal to 6"
The equation sought is:
9x + 5 = 6
Answer:
An equation for the sentence is:
9x + 5 = 6
