Answer:
Step-by-step explanation:
To complete the steps to demonstrate why you multiply by the reciprocal when dividing fractions.
To find
Step 1:
Rewrite it as
.
Step 2:
Multiply the numerator and the denominator by the reciprocal of
.
V = l * w * h
1344 = l * 8 * 12
1344 = 96l
1344/96 = l
14 = l
You can try the ac method.
1. Try to factor a common factor from all terms.
2. Multiply ac.
3. Find two factors of ac that add to b, call them p and q.
4. Rewrite the trinomial with the bx term broken up into into px + qx.
5. Factor by grouping.
