<span>The answer two this question is C.

You can get this answer by multiplying the two polynomials and then simplifying. See the steps below:
(4x^2 - 5)(x + 3) ---> Now multiply the two parenthesis. 
4x^3 - 5x + 12x^2 - 15 ---> Arrange the numbers by decreasing  exponents. 
4x^3 + 12x^2 - 5x - 15

No simplifying can be done since there are no like terms. </span>

Answer: fg(x)=4x^3+12x^2-5x-15

Step-by-step explanation:

Given: f(x)=4x^2-5\text{ and } g(x)=x+3

We know that for any function f(x) and g(x), the multiplication function (fg) (x) is given by :-

fg(x)=f(x)g(x)

Now, for the given functions, we have

fg(x)=(4x^2-5)(x+3)\\\\\Rightarrow\ fg(x)=4x^2(x+3)-5(x+3)\\\\\Rightarrow\ fg(x)=4x^3+12x^2-5x-15

polet [3.4K]

Answer:

156ft of material.

Step-by-step explanation:

Since the garden path borders the garden and is 3 feet wide, it increases the side lengths of his garden by 3 feet on each side. Then we just find the perimeter using the new values:

P=36+36+42+42=156

If this helped, a brainliest answer would be greatly appreciated!

The height of a soccer ball is kicked from the ground can be approximately by the function.
stira [4]

Answer:

1 second

Step-by-step explanation:

y = -16x² + 32x

y = -16(x² - 2x)

y = -16(x² - 2(x)(1) + 1² - 1²)

y = -16(x - 1)² + 16

Max height is when (x-1) = 0

So x = 1
