Hey there,

The first step in solving this problem would have to be to add the two binomials together:

10x² - 4x

Knowing this now we find the GCF which would have to be 2x which goes into both terms.

The factored form would have to be 2x(5x - 2).

The GCF is 2x and the factored form is 2x(5x - 2).

Hope I helped,

So 10% of 12=1.2 divided by

A scientist measures a substance to be 0.8 grams. Calculate the percent of error in the measurement. Show all work for full cred

Volgvan

You'll need to give a bit more information for the question to be answered. You can only calculate the percentage of error if you know what the mass of the substance *should be* and what you've *measured* it to be.

In other words, if a substance has a mass of 0.55 grams and you measure it to be 0.80 grams, then the percent of error would be:

percent of error = { | measured value - actual value | / actual value } x 100%

So, in this case:

percent of error = { | 0.80 - 0.55 | / 0.55 } x 100%
percent of error = { | 0.25 | / 0.55 } x 100%
percent of error = 0.4545 x 100%
percent of error = 45.45%

So, in order to calculate the percent of error, you'll need to know what these two measurements are. Once you know these, plug them into the formula above and you should be all set!

Pls asap... use trigonometry to find the area of a regular 20- gon with each side = 6 in

irga5000 [103]

Answer:

Area of polygon[20 sides] = 1,140 inch² (Approx.)

Step-by-step explanation:

Given;

Number of sides = 20 sides

Length of each side = 6 inch

Find:

Area of polygon[20 sides]

Computation:

Perimeter of polygon[20sides] = 20 x Length of each side

Perimeter of polygon[20sides] = 20 x 6

Perimeter of polygon[20sides] = 120 inch

Apothem[Shortest distance from center] = S / 2tan[180/n]

Apothem[Shortest distance from center] = 6 / 2tan[180/20]

Apothem[Shortest distance from center] = 6 / 2tan[9]

Apothem[Shortest distance from center] = 18.94

Apothem[Shortest distance from center] = 19 inch (Approx.)

Area of polygon[20 sides] = [Perimeter x Apothem] / 2

Area of polygon[20 sides] = [120 x 19] / 2

Area of polygon[20 sides] = 1,140 inch² (Approx.)

Solve the equation for x.

Degger [83]

Answer:

$x=-\frac{11}{8}$

Step-by-step explanation:

Hi there!

$(x - 4) - (x + 7) = 8x$

Open up the parentheses

$x - 4 - x - 7 = 8x$

Combine like terms

$x -x - 4 - 7 = 8x\\-4-7=8x\\-11=8x$

Divide both sides by 8 to isolate $x$

$-\frac{11}{8}=x$

I hope this helps!
