Mathematics

The area of a circle is pi times the radius of the circle squared. The radius of a circle is half the length of the diameter, so you can divide 2x+4 by 2 to get the radius, which would be x+2. Then, you plug it into the formula to get pi times (x+2)^2. You can FOIL that out to get x^2 + 4x + 4 and multiply that by pi, or you can leave it as it was before FOILing.

one positive number is 5 times another number. the difference between the two numbers is 764, find the numbers
damaskus [11]
<h3><u>The first number, x, is equal to 955.</u></h3><h3><u>The second number, y, is equal to 191.</u></h3>

x = 5y

x - y = 764

Because we have a value for x, we can plug it into the second equation to solve for y.

5y - y = 764

Combine like terms.

4y = 764

Divide both sides by 4.

y = 191

Because we have a value for y, we can solve for x.

x = 5(191)

x = 955
