Answer:

20x³ -45x

Step-by-step explanation:

The least common multiple of two expressions is the product of their unique factors.

4x³ -9x = x(4x² -9) = x(2x -3)(2x +3) . . . . factors of 1st expression

10x² -15x = 5x(2x -3) . . . . . . . . . . . . . . . . factors of 2nd expression

The unique factors are 5, x, (2x -3), and (2x +3). Their product is ...

5(4x³ -9x) = 20x³ -45x . . . . least common multiple

Find the values of A and B<br> PLEASE HELP GIVING BRAINLIEST

erastovalidia [21]

Factoring the roots, the values of A and B are given as follows:

A = 3z.

B = 2.

<h3>What are the values of A and B?</h3>

The expression is:

$\sqrt{\frac{45\alpha z^3}{40y}} = \frac{A\sqrt{\alpha z}}{B\sqrt{2y}}$

We have that:

$\frac{45}{40} = \frac{9}{8}$

Hence:

$\sqrt{\frac{45\alpha z^3}{40y}} = \sqrt{\frac{9\alpha z^3}{8}} = \sqrt{\frac{9\alpha z^2 \times z}{4 \times 2}} = \frac{A\sqrt{\alpha z}}{B\sqrt{2y}}$

Hence, comparing the last two equalities:

A = 3z.

B = 2.

A rectangular field is eight times as long as it is wide. If the perimeter of the field is 900 feet, what are the dimensions of

Bas_tet [7]

Answer:

400 feet long

50 feet wide

Step-by-step explanation:

Length = l

Width = w

2l + 2w = 900

l = 8w

Plug the l from the bottom equation into the top equation

2 x 8w+ 2w = 900

16w = 900

Divide both sides by 16

16w/16 = 900/16

w = 50

The width is 50 feet

Now plug the new w into one of the original equations; we'll use the bottom one

l = 8(50)

l = 400
