Answer:

Part 1) f(g(x))=3(x^2)+2

Part 2) g(f(5))=289

Step-by-step explanation:

we know that

A composite function is a function that depends on another function. A composite function is created when one function is substituted into another function

we have

f(x)=3x+2

g(x)=x^{2}

Part 1) Determine f(g(x))

To find f(g(x)) substitute the function g(x) as the variable in function f(x)

so

f(g(x))=3(x^2)+2

Part 2) Determine g(f(x))

To find g(f(x)) substitute the function f(x) as the variable in function g(x)

so

g(f(x))=(3x+2)^2

For x=5

g(f(5))=(3(5)+2)^2

g(f(5))=289

Can somebody help me in this question? It would be very appreciated! :)
Fiesta28 [93]

Answer:

see explanation

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = width × length

let width be w then length is 2w + 3 ( 3 more than twice the width ), then

A = w(2w + 3) ← distribute

   = 2w² + 3w

When w = 4 , then

A = 2(4)² + 3(4)

   = 2(16) + 12

    = 32 + 12

     = 44 ft²

24a²b³ - 28a²a³b³

re-write 24 as 6*4    and  -28 as 7*4

6*4a²b³ + 7*4a²a³b³

factor common terms
