Answer:

450

Step-by-step explanation:

If the perimeter is 90 inches then each side must equal 30 inches. To find the area of a triangle you mulptiply the base by the height and divide by 2. The base is 30 and the height is 30. 30*30=900. 900/2=450.

Solve the inequality.<br> 5x - 7 &lt; 8x + 8<br> The solution set is x |
timofeeve [1]

Answer:

- 5 < x

Step-by-step explanation:

To solve, we need to isolate the variable: x

5x - 7 < 8x + 8

Subtract 5x from both sides

5x -  5x -7 < 8x -5x + 8

- 7 < 3x + 8

Subtract 8 from both sides

- 7 -8 < 3x + 8 -8

-15< 3x

Divide both sides by 3

- 15/3< 3x/3

- 5 < x
