3x² + 6x - 24
Simplify 3.
3(x² + 6x - 8)
Think of x² +2x−8. Factor the expression by grouping. First, we need to rewrite the expression as x² + ax + bx - 8. To find a and b, set up a system to be solved.
- a + b = 2
- ab = 1( −8 ) = −8
Since ab is negative, a and b have opposite signs. Since a+b is positive, the positive number has a greater absolute value than the negative. Show all pairs of integers whose product is −8.
Calculate the sum of each pair.
The solution is the pair that gives sum 2
Rewrite x² + 2x − 8 as (x² − 2x ) + (4x − 8).
Simplify x in the first group and 4 in the second.
Simplify the common term x−2 with the distributive property.
The entire factored expression is rewritten.
3 ( x − 2 )( x + 4 ) ===> Answer
We conclude that the correct option is "B".

the actual answer is 29.111111, which would not be a remainder of 1.
Answer:
k - 2 = 4d - 8
d + 1 = 4d - 8
Step-by-step explanation:
Daniel's age = d
Kevin's age = k
Given that, k = d + 3 -------------- (1)
Two years ago, the age of Daniel = d - 2
Two years ago, the age of Kevin = k - 2
Since, two years ago, Kevin was 4 times as old as
Daniel, k - 2 = 4(d - 2)
Opening the bracket,
k - 2 = 4d - 8
Since the value of k is d + 3 (see (1))
d + 3 - 2 = 4d - 8
d + 1 = 4d - 8
(I am just giving the answer cause I LOVE Linear Equation )
1 + 8 = 4d - d
9 = 3d
9/3 = d
3 = d
Therefore, Daniel's present age is 3 and Kevin's present age = 6

The cost to drive 325 miles is $152.75.
Given: Initial cost = $39
Per mile cost= $0.35
To find: To find the total cost for 325 miles
Concept: Multiplication is the method of finding the product of two or more numbers. It is a primary arithmetic operation that is used quite often in real life.
The cost to drive 325 miles without adding the initial cost = $0.35*325 = $ 113.75
The cost to drive 325 miles while adding the initial cost = $ 113.75 +39 = $ 152.75
