Answer:

A. 2x + 1

Step-by-step explanation:

6x³ - 15x² - 9x

3x (2x² - 5x - 3)

3x (2x² + x - 6x - 3)

3x (x (2x + 1) - 6x - 3)

3x (x (2x + 1) - 3 (2x + 1))

= 3x (2x + 1) (x - 3)

one of the factor of the complete factorization is A. 2x + 1

Answer:

$\tt{}A. \:2x + 1$

Step-by-step explanation:

$\tt{}6 {x}^{3} - 15 {x}^{2} - 9x$

$\tt{}3x \times ( {2x}^{2} - 5x - 3)$

$\tt{}3x \times ( {2x}^{2} + x - 6x - 3)$

$\tt{}3x \times (x \times (2x + 1) \times3 (2x + 1))$

$\tt{}3x \times (2x + 1) \times (x - 3)$

Nate and his friends are building a skateboard ramp for an upcoming contest. The length of the ramp on the blueprint is 7.6 inch

ICE Princess25 [194]

Answer:

30.4 feet.

Step-by-step explanation:

We have been given the length of the ramp on the blueprint is 7.6 inches. The scale on the blueprint is 1 inch to 4 feet. We are asked to find the actual length of the ramp.

We will use proportions to solve our given problem as:

$\frac{\text{Actual length}}{\text{Scale length}}=\frac{4\text{ ft}}{1\text{ inch}}$

Now, we will substitute the scale length of ramp in our proportion as:

$\frac{\text{Actual length}}{7.6 \text{ Inches}}=\frac{4\text{ ft}}{1\text{ inch}}$

$\frac{\text{Actual length}}{7.6 \text{ Inches}}\cdot 7.6 \text{ Inches}=\frac{4\text{ ft}}{1\text{ inch}}\cdot 7.6 \text{ Inches}$

$\text{Actual length}=4\text{ ft}\cdot 7.6$

$\text{Actual length}=30.4\text{ ft}$

Therefore, the actual length of the ramp would be 30.4 feet.
