Given that f(x) = x2 + 8x + 15 and g(x) = x + 5, find f(x) · g(x) and express

sukhopar [10]

The result of $f(x) \times g(x)$ is $x^3 + 13x^2+ 55x+ 75$

<h3>Composite functions</h3>

Composite functions are functions that are gotten by combining multiple functions

<h3>The functions</h3>

The functions are given as:

$f(x) = x^2 + 8x + 15$

$g(x) = x+5$

To calculate f(x) * g(x), we have:

$f(x) \times g(x) = [x^2 + 8x + 15] \times [x + 5]$

Expand the above expression

$f(x) \times g(x) = x^3 + 8x^2 + 15x + 5x^2 + 40x + 75$

Collect like terms

$f(x) \times g(x) = x^3 + 8x^2 + 5x^2+ 15x + 40x + 75$

Evaluate the like terms

$f(x) \times g(x) = x^3 + 13x^2+ 55x+ 75$

Hence, the result of $f(x) \times g(x)$ is $x^3 + 13x^2+ 55x+ 75$

Expression when m=8 and n=7 n+6m

Andrews [41]

All you have to do is plug m and n into the equation:

n+6m

Since n=7, you'll get:

7+6m

And since m=8, you'll get:

7+6(8)

And by doing the order of operations (PEMDAS), you'll start off multiplying 6 and 8, which is 48, then add 7, which is 55.

Your answer should be 55!
