Answer:
The fourth answer choice is the correct one: 2(x - 3)
Step-by-step explanation:
2x²-18x+36/x-6 should be factored, as follows:
2(x²-9x+18) / (x-6) = 2(x - 3) (x - 6) / (x - 6)
Substituting x = 6 would result in division by zero and is thus not allowed.
Remembering this, we can reduce 2(x - 3) (x - 6) / (x - 6) to 2(x - 3) for x≠6.
<span>This problem is an
example of ratio and proportion. A ratio is a comparison between two different
things. You are given the equivalent distance of a 1 2/5
kilometers to 1 mile. Also you are given 4 miles. You are required to find the distance
in kilometers of 4 miles. The solution of this problem is,</span>
1 2/5
kilometers /1 mile = distance/ 4 miles
distance = (4
miles) (1 2/5 kilometers /1 mile)
<u>distance =
28/5 or 5.6 kilometers</u>
<u>There are 5.6
kilometers in 4 miles.</u>
Answer:
3(x - 12)(x + 2)
Step-by-step explanation:
Given
3x² - 30x - 72 ← factor out 3 from each term
= 3(x² - 10x - 24) ← factor the quadratic
Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 12 and + 2 , since
- 12 × 2 = - 24 and - 12 + 2 = - 10 , thus
x² - 10x - 24 = (x - 12)(x + 2) and
3x² - 30x - 72 = 3(x - 12)(x + 2)
Answer:
-2
Step-by-step explanation:
Just use 6-8 and you will get - 2
Check again with - 2+8 you will get positive 6
