Please help me with this is so confusing

The expression for the height of the solid is:

Step-by-step explanation:

Recall that the volume of a rectangular solid is given by:

Where l is the length, w is the width, and h is the height.

We know that the volume is given by the polynomial:

And that the length and width are given by, respectively:

Substitute:

We can solve for h. First, divide both sides by 3x:

Divide each term:

To solve for h, divide both sides by (x - 2):

Since this is a polynomial divided by a binomial in the form of (x - a), we can use synthetic division, where a = 2. This is shown below. Therefore, the expression for the height of the solid is:

step-by-step explanation:

use that smart brain

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
