4 + 2x = 12
-------------------------------------
Take away 4 from both sides:
-------------------------------------
2x = 8
-------------------------------------
Divide by 2 on both sides:
-------------------------------------
x = 4
-------------------------------------
Answer: x = 4
-------------------------------------
The formula to find the surface area of a circle is: pi x radius², so if we square the radius the answer would be 25, then we multiply that by 3.14 and the answer would be around 78.5, so the answer is 78.5.
14 and 28 are two different common denominators for the fractions and we convert both fractions to eighteenths we can subtract 3 eighteenths from 10
so what do you think the answer is
this is just a example
Written form is just how you would usually see a number. So it would be 3,680,010.
