Multiply the terms out:

900xy^{3}  + 144x^{2}y^{3}

You can't do anything else to this because they don't have the same exponents on the variables.

padilas [110]

Answer:

3.6 m

Step-by-step explanation:

Given that :

Length of room = 6

Distance between opposite corners = 7

Width of room :

Using Pythagoras rule:

Opposite ²= hypotenus² + adjacent²

From. The diagram attached :

w² = 7² - 6²

w² = 49 - 36

w² = 13

w = 3.605

w = 3.6 m

The volume of the cube below is 1/8 cm2.
Katen [24]

9514 1404 393

Answer:

  C)  x = 1/2 cm

Step-by-step explanation:

Apparently, we're to assume the units of x are centimeters. The volume of the cube is the product of its dimensions:

  V = x³ = 1/8

Then the value of x is ...

  x = ∛(1/8) = 1/∛8

  x = 1/2

_____

<em>Additional comment</em>

It can be useful to memorize the squares and cubes of small integers. The cubes you see most often are ...

  1³ = 1; 2³ = 8; 3³ = 27; 4³ = 64; 5³ = 125; 6³ = 216; 7³ = 343

Which function is the inverse of ſx) - 2x+ 3?
Sonbull [250]

If f^{-1}(x) is the inverse of f(x), then

f\left(f^{-1}(x)\right) = x

which means

2f^{-1}(x)+3 = x

Solve for f^{-1}(x) :

2f^{-1}(x) + 3 = x \\\\ 2f^{-1}(x) = x - 3 \\\\ f^{-1}(x) = \dfrac{x-3}2 = \boxed{\dfrac12x-\dfrac32}

Please find the value of x in the figure
notka56 [123]

Answer:

Step-by-step explanation:

E is the midpoint of Ac & D is the midpoint of AB

DE = (1/2)BC        {Midpoint theorem}

x +1 = \dfrac{1}{2}(4x - 6)\\\\\\&#10;Multiply \ the \ whole \ equation \  by 2\\\\&#10;2*(x+1) =2*\dfrac{1}{2}*(4x - 6)

2*x + 2*1 = 4x - 6

2x + 2 = 4x - 6

Add 6 to both sides

2x + 2 + 6 = 4x

2x + 8 = 4x

Subtract 2x from both sides

8 = 4x - 2x

2x = 8

Divide both sides by 2

x = 8/2

x = 4
