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.

Inessa [10]

Answer:

<u>1.16 m (approximately)</u>

Step-by-step explanation:

Let x be the width of the path.

Total area = (5+2x)(3+2x) = 39

Expand and simplify

4x²+ 16x+15-39 = 0

4x² + 16x - 24 = 0

Simplify

x² + 4x -6 = 0

Rational factoring does not work, so use quadratic formula

x = +/- sqrt(10) -2

= 1.16 or -5.16 (reject)

= <u>1.16 m (approximately)</u>

The value of k is $(3\sqrt{ 10})/2$

<h3>How to solve the simultaneous equation?</h3>

Given:

x-y=k.............(eq i)

2x²+y²-15..............(eq ii)

We would make y the subject formula in eq ii

2x²+y²-15= 0

2x² + y²= 15

y²= 15-2x²

y= $\sqrt{15-2x^2}$ ...........(eq iii)

Substitute the value of y into eq i

x-( $\sqrt{15-2x^2}$ = k

x- ( $\sqrt{15} - 2x$ = k

k= $(3\sqrt{ 10})/2$
