Triple t ⇒ 3t
add the result to u ⇒ 3t + u
multiply what you have by v ⇒ (3t + u)v
Since it is instructed not to simplify, we perform the distributive property of multiplication.
(3t + u)v = 3tv + uv
Answer: the answer is 12
Step-by-step explanation:
<span>(x+3)^2 = x^2 + 69

x^2 + 6x + 9 - x^2 = x^2 + 69 - x^2
6x + 9 = 69</span>
