Answer:

Step-by-step explanation:
1) Find the Greatest Common Factor (GCF).
1 - What is the largest number that divides evenly into  and
 and  ?
 ?
It is 
2 - What is the highest degree of  that divides evenly into
 that divides evenly into  and
 and  ?
 ?
It is 1, since  is not in every term.
 is not in every term.
3 - Multiplying the results above,
The GCF is 4.
2)  Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

3) Simplify each term in parentheses.

4) Factor out common terms in the first two terms, then in the last two terms.

5)  Factor out the common term  .

Answer:
703.36
Step-by-step explanation:
the formula is v=b×h×pi
pi = 3.14
length: 28
base:8
So base (8) times length (28) times pi (3.14)
8×28×3.14 = 703.36
 
        
             
        
        
        
The system of inequalities is x+y≥250 and 3x+2y≤800.
Step-by-step explanation:
Given, 
People to invite = at least 250 
At least 250 means that the number can increase from 250.
Cups to be provided = only 800 
It means the number cannot exceed 800.
Number of adults = A
Number of children = C
According to given statement; 
x+y≥250
3x+2y≤800
The system of inequalities is x+y≥250 and 3x+2y≤800.
