It depends on the shape or figure your trying to find it for.
Area- the area of a flat or plane figure is the number of unit squares that can be contained in it.
Volume- Is the measure of the amount of space in a closed figure.

The formula for the area of any regular polygon is 1/2 the product of the apothem and the perimeter. The area of a circle is $\pi r^{2}$ with the r standing for "radius".

The formula for the volume of any prism or cylinder is the area of the base times the height of the prism or cylinder. The volume for a sphere is 4/3 the product of $\pi r^{2}$ with the r standing for radius.

There are countless other formulas for volume and area, so if the one you are looking for is not here please comment the formula you're looking for and I'll happily supply you with it!

What value of x makes the equation 3(x-6)-8x=-2+5(2x+1) true ?

Dafna11 [192]

Answer:

x = (-7)/5

Step-by-step explanation:

Solve for x:

3 (x - 6) - 8 x = 5 (2 x + 1) - 2

3 (x - 6) = 3 x - 18:

3 x - 18 - 8 x = 5 (2 x + 1) - 2

Grouping like terms, 3 x - 8 x - 18 = (3 x - 8 x) - 18:

(3 x - 8 x) - 18 = 5 (2 x + 1) - 2

3 x - 8 x = -5 x:

-5 x - 18 = 5 (2 x + 1) - 2

5 (2 x + 1) = 10 x + 5:

-5 x - 18 = 10 x + 5 - 2

Add like terms. 5 - 2 = 3:

-5 x - 18 = 10 x + 3

Subtract 10 x from both sides:

(-5 x - 10 x) - 18 = (10 x - 10 x) + 3

-5 x - 10 x = -15 x:

-15 x - 18 = (10 x - 10 x) + 3

10 x - 10 x = 0:

-15 x - 18 = 3

Add 18 to both sides:

(18 - 18) - 15 x = 18 + 3

18 - 18 = 0:

-15 x = 3 + 18

3 + 18 = 21:

-15 x = 21

Divide both sides of -15 x = 21 by -15:

(-15 x)/(-15) = 21/(-15)

(-15)/(-15) = 1:

x = 21/(-15)

The gcd of 21 and -15 is 3, so 21/(-15) = (3×7)/(3 (-5)) = 3/3×7/(-5) = 7/(-5):

x = 7/(-5)

Multiply numerator and denominator of 7/(-5) by -1:

Answer: x = (-7)/5

How to find common difference of arithmetic sequence given first and last term?

scoundrel [369]

Yeah there is a way... Lemme give a typical question...
Find the common difference of an arithmetic progression whose first term Is 1 and last term is 1023...

First term = T¹ =a
Last term = Tn = a + (n-1)d

Since your given the values of the first and the last term... You can substitute

Tn = 1 + (1023-1)d

1023 = 1 + 1022d

1022d = 1023 - 1

1022d = 1022

common difference = 1...

So there is a way....

You can get the common difference using the two terms given...

Hope this helped...

Write the smaller solution first and larger solution second. (X-2)(3x+3)

saw5 [17]

If this is an equation then write:
x-2=0
x=2

3x+3=0
x=-1

so smaller solution is x= -1 and larger is x=2
