Answer:
B. you need atleast one variable for an algebraic expression.
 an equals sign would make it an algebraic equation, 
just a coefficient and a variable is the most basic algebraic expression. you don't need anything other than those for an expression. you can have more than one number, and more than one operation, but they don't have to be there.

The answer is 88 5/6 .   If you were stuck try turning the fractions into improper fractions and multiply both of them and later divide the numerator by the denominator to have a mixed number.  You can later simplify the fraction to get 88 5/6.  If you need help don't be afraid to tell me in the comments!   Hope this helps :)
        
             
        
        
        
Answer:
7.7
Step-by-step explanation:
The area of the wall is 4 * 2 = 8.
The radius of each clock is 0.3 / 2 = 0.15.
The area of all 4 circles is 4 * (πr²) = 4 * 3.14 * 0.15² = 0.3.
8 - 0.3 = 7.7
