Answer: cd(x) = 4x³ — 2x² + 8x — 4

Step-by-step explanation:

c(x) = 4x - 2

d(x) = x² + 2

Therefore, cd(x) = c(x) × d(x)

cd(x) = (4x - 2)(x² + 2)

= (4x × x²) + (4x × 2) + (-2 × x²) + (-2 × 2)

= 4x³ + 8x -2x² - 4

cd(x) = 4x³ — 2x² + 8x — 4

Hope this helps?

What equation describes the circle that is centered at (8, 3) and has a radius of 9
Sloan [31]

Answer:

<h3> (x-8)²+(y-3)² = 81</h3>

Step-by-step explanation:

The general equation of a circle is expressed as;

(x-a)²+(y-b)² = r² where;

(a, b) is the centre of the circle

r is the radius

Given the centre (8, 3) and the radius of 9, the equation of the circle will be;

(x-a)²+(y-b)² = r²

(x-8)²+(y-3)² = 9²

(x-8)²+(y-3)² = 81

hence the required equation is  (x-8)²+(y-3)² = 81
