Answer:

12x² - 13x - 14

Step-by-step explanation:

 (3x+2)(4x-7)

Multiply  3x by 4x - 7 and +2 by 4x - 7. That is

3x ( 4x -7) + 2 ( 4x - 7)

(3x × 4x)  - (3x × 7 ) + (2× 4x) - (2×7)

= 12x²  - 21x + 8x - 14

Note : -21x + 8x = -13x.

Therefore

= 12x² - 13x - 14

Answer:

You "FOIL" (First, Outer, Inner, Last).

12x^{2}  - 13x - 14

Step-by-step explanation:

You "FOIL" (First, Outer, Inner, Last). Basically, you have to multiple each term by each of the other terms.

(3x+2)(4x-7)

(3x)(4x) + (17)(3x) + (2)(4x) + (2)(-7)

12x^2 - 21x + 8x - 14

12x^2 - 13x - 14

Travka [436]

Answer:

Aidan is 2 miles far from the ending point when he reaches the water station.

Step-by-step explanation:

The locations of the starting point, water station and ending point are (3, 1), (3, 7) and (3, 9), all expressed in miles. First we determine the distances between starting and ending points and between starting point and water station by the Pythagorean Theorem:

From starting point to ending point:

D = \sqrt{(3-3)^{2}+(9-1)^{2}} (Eq. 1)

D = 8\,mi

From starting point to water station:

d = \sqrt{(3-3)^{2}+(7-1)^{2}} (Eq. 2)

d = 6\,mi

The distance between the water station and the ending point is:

s = D-d (Eq. 3)

s = 8\,mi-6\,mi

s = 2\,mi

Hence, Aidan is 2 miles far from the ending point when he reaches the water station.
