Answer: 2x(x+2)−(x+2)

Step-by-step explanation:

Factor out common terms in the first two terms, then in the last two terms.

2x(x+2)−(x+2)

Factor out the common term x+2.

(x+2)(2x−1)

RST is dilated about the origin,O, to creat R’S’T’. Point R is located at (3,9) and point R is located at (1.2, 3.6). Which scal

sashaice [31]

Answer:

The scale factor used is 0.4

Step-by-step explanation:

Given

$R = (3,9)$

$R' = (1.2, 3.6)$

Required

Determine the scale factor of RST

The question can be solved using scale factor formula

Scale factor is calculated as thus;

$Scale\ Factor = \frac{New\ Length}{Old\ Length}$

In this case; R' is the new length and R is the old length

$Scale\ Factor = \frac{R'}{R}$

Substitute the values of R and R'

$Scale\ Factor = \frac{(1.2,3.6)}{(3,9)}$

Factorize the denominator

$Scale\ Factor = \frac{(1.2,3.6)}{2.5(1.2,3.6)}$

$Scale\ Factor = \frac{1}{2.5}$

$Scale\ Factor = 0.4$

<em>Hence, the scale factor used is 0.4</em>

A cone has a diameter of 10 inches. If its height is twice its radius, about what is the volume of the cone in cubic inches? Use

GuDViN [60]

Answer:

C) 261.67 inch³

Step-by-step explanation:

radius = 10/2 = 5

height = 10

Volume = ⅓×pi×r²×h

= ⅓×3.14×5²×10

= 261.6666666667
