7x+2m+25 I believe is the answer
So basically I added the x’s first 3x+4x=7x
Next I added the m’s 7m-5m=2m
That left 25
And a + are left
So the two answers 7x+2m and add +25
7x+2m+25

Given f(x) = 3x + 4 and g(x) = 8x + 1<br> then what is ( f + g )(0))?<br><br> *****HELP*^^^^^^
pochemuha

     •   f(x) = 3x + 4

     •   g(x) = 8x + 1


Sum both functions above:

     (f + g)(x) = f(x) + g(x)

     (f + g)(x) = (3x + 4) + (8x + 1)

     (f + g)(x) = 3x + 8x + 4 + 1

     (f + g)(x) = 11x + 5


Therefore,

     (f + g)(0) = 11 · 0 + 5

     (f + g)(0) = 0 + 5

     (f + g)(0) = 5   <———   this is the answer.


I hope this helps! =)

Which shows the factored form of x2 – 12x – 45? (x 3)(x – 15) (x – 3)(x – 15) (x 3)(x 15) (x – 3)(x 15).
Aleksandr [31]

The factors of the quadratic equation are (x+3) and (x-15).

<h2 /><h2>Given to us</h2>
  • x^2-12x-45\\

<h3>To find</h3>

The factors of x^2-12x-45\\.

<h3 /><h3>Solution</h3>

x^2-12x-45\\

As we can see in the quadratic equation the value of ac is -45x². therefore, we need to divide -12x into two parts such that their sum must give -12x and their product gives us -45x².

therefore, dividing -12x into -15x and 3x,

x^2-15x+3x-45\\

Taking common out,

x^2-15x+3x-45\\x(x-15)+3(x-15)\\(x+3)(x-15)

Hence, the factors of the quadratic equation are (x+3) and (x-15).
