Answer:
3x + y - 3
Step-by-step explanation:
<u>Like Terms</u>: In algebra, like terms are terms that have the same variables and powers.
To simplify this expression and get an expression that is eual to 5x + 3y - 2x - 2y - 3 I used <em>like terms</em> :
(5x - 2x) + (3y - 2y)
(5x - 2x = <em>3x</em>) + (3y - 2y = <em>1y or y</em>)
3x + y
Then we add the <em>- 3 </em>at the end giving us:
<u><em>3x + y - 3</em></u>
To do this divide 5.0 by 0.5. Move the decimal one place to the right. Now do the division. It gives you 10.

Given:
Height of a trapezoidal prism = 10 cm
Base lengths are 3 and 4 cm.
Base height = 2 cm
To find:
The volume of the trapezoidal prism.
Solution:
Base area of a trapezoidal prism

Where, a,b are base lengths and h is the base height.
Putting
, we get


The volume of a trapezoidal prism is:

Where, B is the base area and h is the height of the prism.
Putting
, we get


Therefore, the volume of the trapezoidal prism is 70 cubic cm.
