Answer:

B. A=6 B=-25, C=14

Step-by-step explanation:

(3x -2)(2x-7)

Using FOIL

= 6x^2 - 21x - 4x + 14

= 6x^2 -25x + 14

So a = 6, b = -25 and c = 14

answer

B. A=6 B=-25, C=14

Answer:

Step-by-step explanation:

Expand the factors and compare coefficients of like terms

(3x - 2)(2x - 7)

= 6x² - 21x - 4x + 14

= 6x² - 25x + 14

Compare coefficients to ax² + bx + c

ax² → 6x² ⇒ a = 6

bx → - 25x ⇒ b = - 25

14 → c ⇒ c = 14

a = 6, b= - 25, c = 14 → B

An electrician needs 18.25 feet of wire for each outlet she installs. How man can she install with a 50 ft spool of wire?

jolli1 [7]

Answer:

Step-by-step explanation:

Ok, so if we know how much wire is needed for one outlet, we must figure out how many 18.25s fit into 50 ft of wire.

18.25*2=36.5

18.25*3=54.75 which is over 50 so it cannot possibly be more than 2.

Annie walks 15 feet away from her house and places a mirror on the ground. She backs 4 feet away from the mirror so that she can

artcher [175]

Answer:

The house is 18.75 feet tall

Step-by-step explanation:

The triangles are similar by the AA postulate.

We are given the length of the bottom sides of the triangles, 4 and 15 respectively.

Thus, the ratio is 4:15

We are also given the height of Annie's eyes, which is 5 feet. The height of the side that corresponds to the house is 5, so we can set up a proportion.

$\frac{4}{15} = \frac{5}{x} \\4x = (5*15) = 75\\x = \frac{74}{4} \\x = 18.75$

Thus, the house is 18.75 feet tall.
