May someone help me ASAP?! 24x^4+92x=11x

Lapatulllka [165]

Answer:

x=0 or x= -3/2

Step-by-step explanation:

Step 1: Subtract 11x from both sides.

24x4+92x−11x=11x−11x

24x4+81x=0

Step 2: Factor left side of equation.

3x(2x+3)(4x2−6x+9)=0

Step 3: Set factors equal to 0.

3x=0 or 2x+3=0 or 4x2−6x+9=0

x=0 or x= -3/2

What is the volume of a cylinder with a height of 2 feet and a radius of 6 feet? Use 3.14 for pi. Enter your answer in the box.

erastovalidia [21]

Answer:

$V=226.08\ ft^3$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

where

r is the radius of the base of the cylinder

h is the height of the cylinder

we have

$r=6\ ft\\h=2\ ft\\\pi=3.14$

substitute the given values in the formula

$V=(3.14)(6)^{2}(2)\\ V=226.08\ ft^3$

larisa [96]

Step-by-step explanation:

A. Line up the decimals, then multiply as you would with whole numbers:

$21.33 \\\times 2.04 \\ = 43.5132$

B. Line up the decimals, then add as you would with whole numbers:

Note: These decimals aren't lined up exactly.

$1.115 \\ + 3.18 \\ = 4.295$

$22.061 \\ + 4.295 \\ = 26.356$

$26.356 \\ + 12.2384 \\ = 38.5944$
