<h3>How to find height of a rectangular prism?</h3>
Volume of a rectangular prism = lwh
where
- l = length
- w = width
- h = height
Therefore,
10000 = 25 × 10 × h
10000 = 250h
h = 10000 / 250
h = 40 cm

Step-by-step explanation:
To simplify this, we must combine like terms.
3x, -3x, and 5x will be combined with each other
3 and 7 will be combined
3x-3x+5x= 5x
3+7=10
so our simplified expression is <em><u>5x+10</u></em>
