3| 2a - 4 |  =  0

Divide by 3   --->   | 2a - 4 |  =  0

Usually an absolute value problem has two answers, one when the expression inside the absolute value is positive and the other when the expression inside the absolute value is negative; however, since the absolute value equals zero, there is only one possibility.

--->     2a - 4  =  0

                2a  =  4

                  a  =  2

^ means the following number is an exponent

12 tenths  =  12/10

9 tents  =  9/10

12 tenths + 9 tenths  =  12/10 + 9/10  =  (12 + 9)/10  =  21/10

10¹ = 10

10² = 100

10³ = 1000                     (Simply put, if the exponent is positive, it tells the number of zeros.)

3.16 x 10³  =  3.16 x 1000  =  3160

all the time

    3x^3-9x^2=3x^2(x - 3)

4^8 / 5^8 =65536/390625=0.16777216

2sqrt(x + 5)*sqrt(x + 5)=2(x + 5) =2x + 10

what is 6 1/3+4=10 1/3

1.00E+009 = 1.0 x 10^9

Recriprical of 25=1/25

=2.813 gal/day (gallons per day)

ther is no answer for that it would be 0 anyway

That would be 900/3 which is 300. Does that solve your answer?

0/0 is not a such thing. There is no answer to such a problem.

The square root of four is sixteen.

Expand the following:
(x-4) (x+3) (x-5)

(x-4) (x-5) = (x) (x) + (x) (-5) + (-4) (x) + (-4) (-5) = x^2-5 x-4 x+20 = x^2-9 x+20:
x^2-9 x+20 (x+3)

 | | x^2 | - | 9 x | + | 20
 | | | | x | + | 3
 | | 3 x^2 | - | 27 x | + | 60
x^3 | - | 9 x^2 | + | 20 x | + | 0
x^3 | - | 6 x^2 | - | 7 x | + | 60:
Answer: |x^3 - 6x^2 - 7x + 60

LEAST common multiple of 50, 350 =350

Area of Square=S^2, S=one side

Area of Circle=Radius^2 x Pi

Radius = Diameter / 2
