We move all terms to the left:

9(2x+15)-(45)=0

We multiply parentheses

18x+135-45=0

We add all the numbers together, and all the variables

18x+90=0

We move all terms containing x to the left, all other terms to the right

18x=-90

x=-90/18

x=-5

Answer:

B. $60x^8$

Step-by-step explanation:

$4x^2\sqrt{5x^4} \cdot 3\sqrt{5x^8} =$

$= 4x^2 \times 3 \sqrt{5x^4 \times 5x^8}$

$= 12x^2 \sqrt{25x^{4+8}}$

$= 12x^2 \sqrt{25} \sqrt{x^{12}}$

$= 12x^2 \times 5 \times x^6$

$= 60x^8$

Answer:

see below

Step-by-step explanation:

1. 0 = (r + 1)(r + 8)

Using Zero Product Property, r = -1, r = -8

2. h(r) = (r + 1)(r + 8)

= r² + 9r + 8

= (r + 9/2)² - 81/4 + 8

= (r + 4.5)² - 12.25 (Complete the square)

Vertex: (-4.5, -12.25)

Find the volume of a cylinder with radius 4 m. And height 3 m.

katovenus [111]

$V = \pi r^25$

Plug in the values

r = 4 ; h = 3

$V= \pi *4^2*3

V = 3.14 * 16 * 3

V = 150.72$

So approximately 150.7
