Simplify the product using the Distributive Property
(a - 4)(a - 1)

Hope this helped .......................

6(2x + 5y)6 (2x) = 12x6 (5y) = 30y12x + 30y

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
