Answer:


Step-by-step explanation:
The question relates with rules of indices
(a) The give expression is presented as follows;

By expanding the expression, we get;

Collecting like terms gives;


(b) The given expression is presented as follows;

Therefore, we get;

Collecting like terms gives;



First change the mixed fraction into an improper fraction
7 1/2 = 15/2
Next, change multiply 2 to both numerator and denominator
15 x 2 = 30
2 x 2 = 4
30/4
Each piece needs 3/4 of an inch. Divide 30 with 3
30/3 = 10
c) 10 pieces is your answer
