that website had the equations i was looking for

FV (future value) is an importtant value that needs to be preserved. The top part of  the formula may be zero but not always.

the software it is going in has to solve for all values. i have 2/3 but cant figure out i and n

order of operations division before addition

10/10+10/10=2

the equation for the area of a circle is A=πr²

r is half the diameter and the aproxomation of π is 3.14

so A or area is 3.14 times 12 which is 37.68

explaining infinity is a little complicated as i do not know what grade you are in so you get the complicated version(ps if you are not in grade 12 yet this will impress you teacher)

infinity is essentialy all numbers (i.e. no matter what number you give there are more after it, so infinity plus, minus, times or divided by anything is still infinity) but, and here is where it gets complicated, there are some infinities that are bigger than others for example there are more real numbers between 1 and 2 than there are the infinite mumber of whole numbers

1-1.1

2-1.01

3-1.11

4-1.011

5-1.101

....

6057237-1.9035248

see no matter how high you count in whole nubers there are more real numbers as all you need to do is make sure 1 digit is different and it is another number

x=1 and x=-3 so it is (x-1) and (x+3)

added together -1 and 3 equal 2 and when multiplied equal -3 so look for the equation with their product (-3) as the constant (no variable) and their sum (2) as the coeficient of the middle term

so the correct answer is b.

to check

(x-1)(x+3)

x^2 + 3x - x - 3

x^2 + 2x - 3

4^5-8*25-50+7=781

10/25=2/5 so 1/25+2/5 can be written as 1/25+10/25 which equals 11/25

5y-3/5=4/5 first add 3/5 to both sides

5y=4/5+3/5 simplify

5y=7/5 divide both sides by 5

y=7/5/5 simplify

y=7/25

you just did :p

volume of a rectangular prism (which a cube is) is length X width X height

1/2 * 25 = 25/2

25/2 =12 1/2

12 1/2= 12 + 1/2

12+1/2=12.5
