Answer:
Step-by-step explanation:
The given expression is .
We factor the GCF to get:
This can be rewritten as:
We can observe that the quadratic trinomial is a perfect square)
Therefore the completely factored form of the given trinomial is
The formula for a trapezoid is a=a+b/2 x h
so plug that back into the equation and you get
15=10/2 *h
15=5*h
from here, you know that 15/5 equals 3 and therefore the height of the trapezoid is 3.
Good Luck on ur Big Test!
