Question

Expand and simplify a(t+4)-a(4-3t

Answer 1

4at

Explanation:

1. Distribute. You well get at+4a-4a+3at.

2. Eliminate the opposites (+4a and -4a cancel out to equal 0, which can then be excluded from the equation). You will get at+3at.

3. Add. at+3at=4at

Answer 2

Explanation:

Use distributive property

a(t+4) - a(4 - 3t) = a*t + a*4 +(- a) * 4 - (-a)*3t

= at+ 4a - 4a + 3at {combine like terms}

= at + 3at + 4a - 4a {add /subtract like terms}

= 4at
