<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

Svetllana [295]
26 by 9
Area = L*W
Area = 26 * 9
Area = 234 square feet but there are 2 such walls
Area = 234 * 2
Area = 468 square feet total for these walls.

18 by 9
Area = L*W
Area = 18 * 9
Area = 162 square feet

Total area = 468 + 162 = 630 square feet.

1 gallon covers 250 square feet
x gallon covers 630 square feet


1/x = 250/630
250 x = 1 * 630
x = 630 / 250
x = 2.52 gallons. It is best that she buy 3 gallons of paint.

Given f (x )equals 2 x minus 5 and g (x )equals 5 x squared​, first find f plus g​, f minus g​, ​fg, and StartFraction f Over g
baherus [9]

Answer:

(f + g)(x) = 5x² + 2x - 5

Domain: All real numbers

(f - g)(x) = -5x² + 2x - 5

Domain: All real numbers

(fg)(x) = 10x³ - 25x²

Domain: All real numbers

(f/g)(x) = \frac{2x-5}{5x^2}

Domain: (negative infinity, 0)U(0, positive infinity)

Step-by-step explanation:

For f + g, we are simply adding the 2 together

<em>Domain: All values of x work, as any value x outputs any value y</em>

For f - g, we are simply subtracting the 2 together

<em>Domain: All values of x work, as any value x outputs any value y</em>

For f times g, we are simply multiplying (distributing) the 2 together

<em>Domain: All values of x work, as any value x outputs any value y</em>

For f divided by g, we are simply dividing (fraction) the 2 together

<em>Domain: All values except for 0 work (undefined error), so asymptote at x = 0</em>
