Find the LCM of (6x - 18) and (2x² - 6x)? Please explain as well I really need this answer.

1 answer:

3 0

The least common multiple can be found a couple of ways. For this, it is probably easiest to identify the unique factors of each expression.
(6x -18) = 6(x -3) = 2*3*(x -3)

(2x² -6x) = 2x(x -3)

Then the unique factors are 2, 3, x, (x -3). Their product is the LCM:
LCM = 6x(x -3) = 6x² -18x

_____
If one or more of the factors is raised to a power other than 1, use the highest power of that factor in the final product.

Step-by-step explanation:

Circumference (C):

$C = 2\pi r = 2\pi(5\:\text{ft}) = 31.4\:\text{ft}$

Area (A):

$A = \pi r^2 = \pi(5\:\text{ft})^2 = 78.5\:\text{ft}^2$

Answer:

13.2 miles

Step-by-step explanation:

To solve this, we will need to first solve for the base of the triangle and then use the information we find to solve for the shortest route.

(5.5 + 3.5)² + b² = 15²

9² + b² = 15²

81 + b² = 225

b² = 144

b = 12

Now that we know that the base is 12 miles, we can use that and the 5.5 miles in between Adamsburg and Chenoa to find the shortest route (hypotenuse).

5.5² + 12² = c²

30.25 + 144 = c²

174.25 = c²

13.2 ≈ c

Therefore, the shortest route from Chenoa to Robertsville is about 13.2 miles.
