Answer:

x^2+ 18x -130=0

Step-by-step explanation:

Given

See attachment for diagram

Required

The equation to find x

First, calculate the area of the big rectangle using:

Area = Length * Width

So:

A_1 = (x + 6) * (3x - 2)

The smaller rectangle

A_2 = (x - 1) * (2x)

The difference between this areas give the area of the shaded region.

So:

A_1 - A_1 = 118

(x+6)*(3x-2) - (x-1)*2x = 118

Open brackets

3x^2 - 2x + 18x -12 -2x^2 +2x = 118

Collect like terms

3x^2 -2x^2- 2x +2x+ 18x -12   - 118=0

x^2+ 18x -130=0

<em>The above equation can be used to solve for x</em>

Which two numbers on the number line have an absolute value of 1.75?
Harrizon [31]

The absolute value of a number is the distance the number is from zero on the number line. Only one number is 0 units from 0. It is zero. For all other distances, there are always two numbers. Example: The two numbers a distance of 1 unit from zero are -1 and 1. Example: The two numbers a distance of 4.5 units from zero are -4.5 and 4.5.

In your case, the two numbers a distance of 1.75 units from zero are -1.75 and 1.75. Find -1.75 between -1.5 and -2 and place a dot there. Find 1.75 between 1.5 and 2 and place a dot there.

Andy drove 840 miles in 12 hours. How far could he drive in 3 hours?​
liraira [26]
To answer this, we need to first find the rate and the multiply it by 3. 840/12 = 70 miles per hour. Then multiply it by 3. 70*3=210 miles. Another way we can do it is that we can divide 840 by 4 because 12 hours / 4 = 3 hours. 840/4 = 210 miles.
