Using the function attached. Find (f+G)(x)

Mathematics
1 answer:

We have been given two functions f(x)=-8x^3+5x^2+7x+4 and g(x)=8x^3-2x+3. We are asked to find (f+g)(x).

We will use composite function property (f+g)(x)=f(x)+g(x) to solve our given problem.

(f+g)(x)=-8x^3+5x^2+7x+4+8x^3-2x+3  

Now we will combine like terms as:

(f+g)(x)=-8x^3+8x^3+5x^2+7x-2x+4+3

(f+g)(x)=5x^2+5x+7

Therefore, the value of  (f+g)(x) would be 5x^2+5x+7.

Add.<br><br> 5/8+1/5<br><br> Enter your answer as a fraction in simplest form. no guessing ;)

First of all we want to find a common denominator so we can add them together.

40 is our Lowest Common Multiple.

5/8 = 25/40
1/5 = 8/40

25/40 + 8/40 = 33/40

The length of a postage stamp is
AleksAgata [21]
<h3>Answer: Choice B</h3><h3>2W+2( W+4 1/4) = 124 1/2</h3>

=========================================

Explanation:

L = length

W = width

"The length is 4 1/4 longer than the width" (paraphrase) so

L = W + 4 1/4

This means,

P = perimeter = 124 1/2

P = 2L+2W

2L+2W = P

2W+2L = P

2W+2( L ) = P

2W+2( W+4 1/4) = 124 1/2
