Answer:

x = 2.

Step-by-step explanation:

I am taking this to mean

2^3 * x^3 = (2 + x)^3

8x^3 = (2 + x)(4 + 4x + x^2)

8x^3 = 8 + 8x + 2x^2 + 4x + 4x^2 + x^3

7x^3 - 6x^2 - 12x - 8 = 0

7(2)^3 - 6(2)^2 - 12(2) - 8

= 56 - 24 - 24 - 8 = 0

x = 2.

This is the only real root.

Which expression is equivalent to (4p^-4 q)^-2/ 10pq^-3?

Anit [1.1K]

Answer:

$\dfrac{p^{7} q}{160}$

Step-by-step explanation:

$\dfrac{(4p^-4 q)^-2}{10pq^-3} =$

$= \dfrac{4^{-2}p^{-4\times (-2)} q^{-2}}{10pq^-3}$

$= \dfrac{4^{-2}}{10}p^{8-1} q^{-2-(-3)}$

$= \dfrac{1}{4^2 \times 10}p^{7} q^{-2 + 3}$

$= \dfrac{1}{160}p^{7} q$

$= \dfrac{p^{7} q}{160}$

A rectangular rug has a perimeter of 460 meters. The width of the rug is five meters more than 4 times the length. Find the

Paladinen [302]

Answer:

Length = 45 m

Width = 185 m

Step-by-step explanation:

Given:

Perimeter of rectangular rug = 460 m

width of the rug is five meters more than 4 times the length

To find:

Width and length of rug = ?

Solution:

Let the length = $l$ m

As per given statement,

Width = $4l+5$ m

Formula for perimeter of a rectangle = $2\times (Length +Width)$

$460=2\times (l+4l+5)\\\Rightarrow 230 = 5l+5\\\Rightarrow l = \dfrac{225}{5} = 45\ m$

Width = $4l+5$ m

Width = $4\times 45+5 = 185\ m$

So, the answer is:

Length = 45 m

Width = 185 m

Write the standard form of the equation of the circle with radius 7 and center (5,−7).

olya-2409 [2.1K]

Answer:

$(x-5)^2+(y+7)^2=49$

Step-by-step explanation:

Use $(x-h)^2+(y-k)^2=r^2$ for the equation of a circle in standard form with radius $r$ and center $(h,k)$ . Therefore, the equation of the circle in standard form is $(x-5)^2+(y+7)^2=49$
