Answer:

OPTION C: (x - 5)(x + 6)

Step-by-step explanation:

Given: (x - 3)(x + 4) - 18

Product of (x - 3) and (x + 4) = x² + 4x - 3x - 12

Therefore, (x - 3)(x + 4) - 18 = x² + x - 30

This is a quadratic equation and the roots are x = 5, -6.

This can be written as binomials as:

(x - 5)(x + 6) which is the required answer.

So, OPTION C is the answer.

In 4 days your family drive 5/7 of a trip. Your rate of travel is the same throughout the trip. The total trip is 1250 miles. How many more days until you reach your destination?

Find the amount traveled in one day by dividing

(5/7)/4 = 5/28 of the trip

How many days would it take to add up to 1

1/(5/28) = 5.6 days total

since we already traveled for 4 days, we have 1.6 more days to go

Answer:

6x^2 +12x -1

Step-by-step explanation:

The perimeter is the sum of the two leg lengths and the base length:

P = 2(3x^2 +4x +2) +(4x -5)

= 6x^2 +8x +4 +4x -5

P = 6x^2 +12x -1
