Answer:

The area of a parallelogram is: 96 cm²

Step-by-step explanation:

Given

  • The base of a parallelogram b = 12 cm
  • The height of a parallelogram h = 8 cm

To determine

The area of a parallelogram A = ?

Using the formula to calculate the area of a parallelogram

A = bh

here

  • b is the base of a parallelogram
  • h is the height of a parallelogram

so substituting b = 12 and h = 8 in the equation

A = bh

A = 12×8

A = 96 cm²

Therefore, the area of a parallelogram is: 96 cm²

Values for the area A of the rectangle shown are 12 ≤ A ≤ 36.
Step2247 [10]

A compound inequality is used to combined multiple inequalities.

  • <em>The compound inequality is: </em>12 \le 6x \le 36<em>.</em>
  • <em>The solution to the compound inequality is: </em>2 \le x \le 6<em />

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

Solve the following:<br> a) 4x 3= 2x + 7<br><br> b) 2x+6= 7x14
nikdorinn [45]
<h2><u>Correct question</u> : 4x - 3 = 2x + 7 </h2>

<h2><u>Solution</u> : 4x - 3 = 2x + 7 </h2>

4x - 2x = 7 + 3 \\  \\ 2x = 10 \\  \\ x =  \frac{10}{2}  \\  \\ x = 5.

<h2>•••••••••••••••••••••••••••••••••••••••</h2>

<h2><u>Correct Question</u> : 2x + 6 = 7x - 14</h2>

<h2><u>Solution</u> : 2x + 6 = 7x - 14</h2>

2x - 7x =  - 14 - 6 \\  \\  - 5x =  - 20 \\  \\ x =  \frac{20}{5}  \\  \\ x = 4.
