Values for the area A of the rectangle shown are 12 ≤ A ≤ 36.

Step2247 [10]

A compound inequality is used to combined multiple inequalities.

The compound inequality is: $12 \le 6x \le 36$ .
The solution to the compound inequality is: $2 \le x \le 6$

We have:

$12 \le A \le 36$

$Length = 2x$

$Width = 3$

The area of the rectangle is:

$A = Length \times Width$

So, we have:

$A =2x \times 3$

$A = 6x$

Substitute 6x for A in $12 \le A \le 36$

$12 \le 6x \le 36$

Divide through by 6

$2 \le x \le 6$

Hence,

The compound inequality is: $12 \le 6x \le 36$ .
The solution to the compound inequality is: $2 \le x \le 6$

Answer:

x = -15/2

Step-by-step explanation:

For this problem, we will simply use equation properties to solve for x.

2x - 5 = -20

2x - 5 + 5 = -20 + 5

2x = -15 ( Add positive 5 to both sides )

2x * (1/2) = -15 * (1/2)

x = -15/2 ( Multiply both sides by 1/2)

Hence, the solution to x is -15 / 2.

Cheers.
