Answer:

-12x+18x²

Step-by-step explanation:

Given: -3x(4-6x)

Distributive property of multiplication under which a number is multiplied by the sum of two number, the first number can be distributed to both of those number.

∴  -3x(4-6x)

solving it by using distributive property

= (-3x\times 4)-(-3x\times 6x)

= -(12x) + 18x^{2}

Opening parenthesis

=  -12x+18x^{2}

Hence, -12x+18x^{2} is the result after using distributive property.

Answer:

18 units

Step-by-step explanation:

Hello, I can help you with this.

Step 1

identify

we have a equation, let's look  it

A=6s2

The surface area A of a cube=6(area of a face)

area of face= side*side

so

Area=6*side*side

Step 2

isolate side from the equation

side^{2}=\frac{Area}{6}\\side=+\sqrt{\frac{Area}{6}}

we are looking for a distance, so , we will use only the positive root

Step 3

replace the value of 1944 square units into the equation

side=+\sqrt{\frac{Area}{6}}\\side=+\sqrt{\frac{1944}{6}}\\side=\sqrt{324}\\\\side=18\\

so, the value x of a side of a cube with a total

the side of a cube is 18 units  when the surface area of the cube shown is 1944 units2

Have a good day.
