Answer:
see below
Step-by-step explanation:
80 - 71 = 9
That means 9 studied neither language
25+14 = 39 studied only 1 language
71 - 39 =32
32 studied both
we have

Find the roots
Equate the function to zero

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side.


Rewrite as perfect squares

Square root both sides




therefore
<u>the answer is</u>

Answer:

Step-by-step explanation:
V = (6

Can also be solved by counting the fractional cubes.
1) 3t+18
= 3(t+6)
2) 6m-24
=6(m-4)
3) 10t^2+30t
= 10t(t+3)
4) 12xp-20x
= 4x(3p-5)
The formula for volume is height times width times depth. The formula is 6*3*2. 6*3 is 18 and 18*2 is 36. The answer is 36.
