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

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: $2 \le x \le 6$

Please help me with the circled ones !

TiliK225 [7]

i can only help you with the volume of #5.

So the volume of a cylinder is = πr²h.

First , put the numbers in the equation.

π(6)² (14)

Next you solve.

π(6)²(14) = 36 (14) π = 504π

V= 504π

Why is 4 laps in 10 minutes and 6 laps in 15 minutes proportional

Shtirlitz [24]

If you break it down it goes to 2 laps every 5 minutes. So any set that follows this "pattern" would be proportional
