The correct answer is B) (2x-7)(x+4)=0. If you were to FOIL (First, Outer, Inner, Last) the answer, you would get 2x^2+1x-28=0.
Step by step:
(2x-7)(x+4)=0
FOIL it.
2x^2+8x-7x-28=0
Combine the two middle terms.
2x^2+1x-28=0
Move -28 and 1x over to the right side of the equation.
2x^2=28-x

A restaurant has 75% of its tables being used. Which ratio compares the used tables with all the tables in the restaurant?
Bogdan [553]
75%=75/100=75:100=3/4

4-3=1

1/4=tables not used.

1/4=25/100=25:100

So....25:75 = not used tables : used tables

Henry had 15 quarters. He gave his sister 4 quarters. How much money does he have now??
telo118 [61]

Answer:

$2.75

Step-by-step explanation:

A quarter's value as placed on it by the U.S. Treasury Department is $0.25, or 1/4 of a dollar.

Henry had 15 quarters, in which he gives his sister 4: 15 - 4 = 11

Henry now has 11 quarters. Multiply 11 with 0.25: 11 x 0.25 = 2.75

Henry has $2.75
