F(x)=-5x^2+4x-9 g(x)=8x^2-3x-4 find (f+g)(x)

Given:

The functions are

To find:

The value of (f+g)(x).

Solution:

We know that,

Putting the given functions, we get

On combining like terms, we get

Therefore, the required function is .

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
