Using the Pythagoras theorem

8^2 = 5^2 + x^2   where x = 1/2 length of the base

x^2 = 64-25 = 39

x = = sqrt39 = 6.24

so base length = 2*6.24 = 12.5 cm to nearest tenth

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

Can someone help me <br><br> 1.3x-338
Olegator [25]

Answer:

Equivalent expressions are expressions which are equal. This means they simplify to the same expression. Simplify the two expressions -1.3x - (-8.9x) = 7.6x and -1.3 + (-8.9X) = -10.2x.

Then simplify each option to determine if it is equal -1.3x - (-8.9x), -1.3 + (-8.9X) or neither:

−1.3x−8.9x  = -10.2x. This is equivalent to  -1.3 + (-8.9X) .

8.9x+(−1.3x)  = 7.6x This is equivalent to  -1.3x - (-8.9x) .

−8.9x+(−1.3x)  = -10.2x This is equivalent to  -1.3 + (-8.9X) .

8.9x−(−1.3x)  = 10.2x Neither

−1.3x+8.9x  = 7.6x This is equivalent to  -1.3x - (-8.9x)  .

−8.9x+1.3x = -7.6x Neither
