Answer:
A. =4x3+9x2−25x+12
Step-by-step explanation:
(x+4)(4x−3)(x−1)
=((x+4)(4x−3))(x+−1)
=((x+4)(4x−3))(x)+((x+4)(4x−3))(−1)
=4x3+13x2−12x−4x2−13x+12
=4x3+9x2−25x+12
Answer: 77
<u>Step-by-step explanation:</u>
varies directly means: 
Step 1: solve for k ⇒ ⇒ 7 = k
Step 2: input the given value and the k-value to find the unknown value:
