Equation:

x(x - 5) + 3(x + 5)

Steps:

x(x - 5) + 3(x + 5)

Expand:

x(x - 5 ): x^2 - 5x

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

Expand:

3(x + 5): 3x + 15

x^2 - 5x + 3x + 15

Add Similar Elements:

-5x + 3x

= -2x

Answer x^2 - 2x + 15 Doesn't Factor

Hope that helps!!! : )

What is the cube root of 216x^9y^18?

PilotLPTM [1.2K]

Answer:

The cube root of given expression is $6x^3y^6$ .

Step-by-step explanation:

The given expression is

$\sqrt[3]{216x^9y^{18}}$

It can be written as

Use the exponent property: $a^{mn}=(a^m)^n$

$\sqrt[3]{216x^9y^{18}}=\sqrt[3]{6^3(x^3)^3(y^6)^{3}}$

$\sqrt[3]{216x^9y^{18}}=\sqrt[3]{(6x^3y^6)^{3}}$

$\sqrt[3]{216x^9y^{18}}=6x^3y^6$

Therefore the cube root of given expression is $6x^3y^6$ .

Referring to the Fig. in Question #42, give the coordinates

iragen [17]

Answer:

(x, y) = (0, -3)

Step-by-step explanation:

The point Y is on the y-axis. Its x-coordinate will be zero, since it is neither left nor right of the y-axis.

The point Y is 3 units below the x-axis, so its y-coordinate is -3. This is the value you can read on the y-axis next to point Y.

(x, y) = (0, -3)

_____

U(-5, 0)

V(-3, 3)

W(5, 5)

X(-4, -5)

Y(0, -3)

Z(2, -1)

It is a good idea to learn to read coordinates from a graph. You will be doing it a lot. The x-coordinate is the number of units right of the y-axis. The y-coordinate is the number of units up from the x-axis. Left or down makes the coordinate negative.
