Answer:
2/5
Step-by-step explanation:
in 4/10, both the numerator (4) and denominator (5) are multiples of 2, as 4 = 2 * 2 and 10 = 2 * 5. thus, we can divide both the numerator and denominator by 2 to get
(4/2) / (10/2) = 2/5 as our answer.

Answer:
100 - 4q²
Step-by-step explanation:
(10 - 2q)(10 + 2q)
each term in the second factor is multiplied by each term in the first factor.
10(10 + 2q) - 2q(10 + 2q) ← distribute parenthesis
= 100 + 20q - 20q - 4q² ← collect like terms
= 100 - 4q²
