Answer:

the unknown, [?], has the value -18.

Step-by-step explanation:

Perform the indicated multiplication on the left side:

-14a - 18b = -14a + [?]b

Adding 14a to both sides, we eliminate a:

-18b = [?]b

Thus, the unknown, [?], has the value -18.

if each side of the cube shown above has the same length as the measured side what is the approximate volume of the cube
klemol [59]

Answer:

The measured side is not shown, so i will answer in a general way.

A cube is a 3-dimensional object with 6 square faces.

You know that all the sides of a square have the same length, then is the same for the cube.

To calculate the volume of a cube, we start with the area of the base.

The base is a square of sidelength L (Suppose that L is the length of the measured side)

The area of the base is:

A = L^2.

To find the volume, we must multiply the area of the base by the height of the fire (because the section of the base does not change).

And the height of the cube is also L.

Then the volume is:

V = L*a = L^3

The formula for estimating the number, N, of a certain product sold is N = 8800ln(7t + 9), where t is the number of years after
arsen [322]
To determine or predict the expected number of sales after 2 years, we substitute 2 to the t of the givne equation.
                           N = (8800)xln(7(2) + 9)
                                N = 27,592.34
Thus, it is expected that the number of sales after 2 years is 27,592 units.
