Answer:

(3x + 5)(9x^2 - 15x + 25)

Step-by-step explanation:

27x^3 + 125

= (3x)^3 + 5^3

= (3x + 5) ((3x)^2 - (3x)(5) + 5^2)

= (3x + 5)(9x^2 - 15x + 25)

FYI: a³ + b³ = (a + b)(a² – ab + b²)

Answer:

Step-by-step explanation:

This is given in the form : a³ + b³

Identity :

a³ + b³ = (a + b)(a² - ab + b²)

Solving :

27x³ + 125
(3x)³ + (5)³
<u>(3x + 5)(9x² - 15x + 25)</u>

What expression is equivalent to

kaheart [24]

Answer:

Option (2)

Step-by-step explanation:

Given expression is $\sqrt[3]{64a^6b^7c^9}$

By simplifying this expression,

$\sqrt[3]{64a^6b^7c^9}=\sqrt[3]{(4)^3(a^2)^3(b^2)^3(b)(c^3)^3}$

$=(4a^2b^2c^3)\sqrt[3]{b}$

Option (1)

$2abc^2\sqrt[3]{4a^2b^3c}$ = $2ab^2c^2\sqrt[3]{a^2c}$

Option (2)

$4a^2b^2c^3(\sqrt[3]{b})$ [Fully simplified form]

Option (3)

$8a^3b^3c^4(\sqrt[3]{bc} )$ [Fully simplified form]

Option (4)

$8a^2b^2c^3(\sqrt[3]{b})$

Expression given in Option (2) is equivalent to the given expression.

Option (2) will be the answer.

Answer:

The complete table will be:

x y

1 5

0.8 4

0.4 2

Step-by-step explanation:

Given rule is:

y = 5x

In the given rule, x is multiplied by 5 to get the values of y. The same rule can be manipulated to find the value of x in terms of y.

$\frac{y}{5} = \frac{5x}{5}\\x = \frac{y}{5}$

Putting y = 5

$x = \frac{y}{5}\\x = \frac{5}{5}\\x = 1$

Putting y = 4

$x = \frac{y}{5}\\x = \frac{4}{5}\\x = 0.8$

Putting y = 2

$x = \frac{2}{5}\\x = 0.4$

Hence,

The complete table will be:

x y

1 5

0.8 4

0.4 2
