Answer:

A

Step-by-step explanation:

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

f(x) + g(x)

Plz help me!!!!!!!!!!
Studentka2010 [4]

Answer:   a³ - 218

<u>Step-by-step explanation:</u>

  (a - 6)(a² + 6a + 36)

= a(a² + 6a + 36) -6(a² + 6a + 36)

= a³ + 6a² + 36a

 <u>     -  6a² -  36a - 218</u>

= a³ + 0a² +  0a  - 218

= a³ - 218

F(x) = 3. 7 – 2x g(x) = 0. 25x – 5 What is f(x) g(x)? h(x) = 3. 95x – 7 h(x) = 8. 7 – 2. 25x h(x) = –1. 3 – 1. 75x h(x) = 3. 95

To solve the problem we must know about Like Terms.

<h3>What are Like Terms?</h3>

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

The solution to the problem is (-1.7x-1.3).

Given to us

  • f(x) = 3.7 - 2x
  • g(x) = 0.25x - 5

To find

f(x) + g(x)

To solve the problem we will put the functions as given to us,

f(x)+g(x)\\= ( 3.7 - 2x)+( 0.25x - 5)

Open brackets,

=3.7 - 2x+ 0.25x - 5

<h3>Like Terms</h3>

Solve the like terms,

=3.7 - 2x+ 0.25x - 5\\\\=0.25x-2x-5+3.7\\\\=-1.75x-1.3

Hence, the solution to the problem is (-1.7x-1.3).

Step-by-step explanation:

Step 1: Factor left side of the  equation.

(3x−2)(2x+1)=0

Step 2: Set factors equal to 0.

3x−2=0 or 2x+1=0

x=\frac{2}{3}      or x=\frac{-1}{2}

Dennis_Churaev [7]

Slope of line that is perpendicular to the  line y = 2x - 6,

m=-\dfrac{1}{2}

Line passes through (1,5).

Equation of line will be,

y-5=m(x-1)\\y-5=-1/2{x-1}\\2y-10=-x+1\\2y=11-x
