The side length, s, of a cube is 3x 2y. If V = s3, what is the volume of the cube? 3x3 18x2y 36xy2 8y3 27x3 54x2y 18xy2 2y3 27x3

uranmaximum [27]

The volume of the cube is 27x³ + 8y³ +54x²y + 36xy².

<h2>Volume of cube </h2>

The volume of a cube is the cube of its side.

$\rm{ Volume\ of\ cube = (side)^3$

<h2>Given to us</h2>

side length, s = (3x+2y)

Volume, V = s³

<h3>Algebraic Identity</h3>

$(a+b)^3= a^3 +b^3 +3a^2b+3ab^2$

<h3>The volume of the cube</h3>

$\begin{aligned}Volume &= s^3\\&= (3x+2y)^3\end{aligned}$

Applying algebraic Identity,

$=(3x+2y)^3\\\\ =(3x)^3+(2y)^3+[3\times (3y)^2 \times2y]+[3 \times 3x \times(2y)^2]\\\\= 27x^3 + 8y^3 +54x^2y +36xy^2$

Hence, the volume of the cube is 27x³ + 8y³ +54x²y + 36xy².

Solve for x 38=3x+35

olganol [36]

Answer:

x = 1

Step-by-step explanation:

Keep the variable left alone by removing any numbers next to it-

3x = 33

Divide each side by 3 to keep x by itself

3x/3 = x

3/3 = 1

x = 1

Simplify-

x = 1

What is the circumference of the half circle?

Gelneren [198K]

Answer:

4π cm

Step-by-step explanation:

<u>GIVEN :-</u>

Diameter of half circle = 8cm

Circumference of half circle

<u>FACTS TO KNOW BEFORE SOLVING :-</u>

Circumference of a circle with radius 'r' is = $2\pi r$

⇒ Circumference of half-circle with radius 'r' = $\frac{2\pi r}{2} = \pi r$

<u>SOLUTION :-</u>

Radius = $\frac{Diameter}{2} = \frac{8}{2} = 4$

So , Circumference of half-circle = $\pi \times 4 = 4\pi$ cm
