Answer:

Choice A

Step-by-step explanation:

I would recommend starting off by using the distributive property.

(7x + 5)(2x³ - 4x² + 9x - 3) = 7x(2x³ - 4x² + 9x - 3) + 5(2x³ - 4x² + 9x - 3)

then simplify

= (14x^4 - 28x³ + 63x² - 21x) + (10x³ - 20x² + 45x - 15)

Now add it all together

= 14x^4 - 18x³ + 43x² + 24x - 15

The answer is choice A

Find the area of the composite shape

Alexxandr [17]

Answer:

$13.735$ $ft^{2}$

Step-by-step explanation:

Area of a circle.

$A=\pi r^{2}$

$r=d/2\\r=8/2\\r=4$

$A=\pi \times 4^{2}$

$A=16\pi$

$A \approx 50.2654824574$

Area of a square.

$A=s^{2}$

$A=8^{2}$

$A=64$

Subtract the area of the square with the area of the circle.

$64-50.2654824574$

$= 13.7345175426$

I hope it helps.

Brainliest much appreciated.

What is the average rate of change of the function f(x)=5(2)^x from x = 1 to x = 5?

Mila [183]

Average rate of change refers to the slope of a function/equation.
To solve this, plug in for both x values and calculate the average, or mean.

x = 1
f(1) = 5(2)^1
= 5(2)
= 10

x = 5
f(5) = 5(2)^5
= 5(32)
= 160

Now, you calculate the average:
10 + 160 = 170
Divide by 2 and you get 85.
