Given: X= 0.234523452345..... Is X rational or irrational? a If X is rational, rewrite it in a fraction.
Evgesh-ka [11]

Answer:

0.234523452345 as a fraction equals 234523452345/1000000000000

Step-by-step explanation:

To write 0.234523452345 as a fraction you have to write 0.234523452345 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.234523452345 = 0.234523452345/1 = 2.34523452345/10 = 23.4523452345/100 = 234.523452345/1000 = 2345.23452345/10000 = 23452.3452345/100000 = 234523.452345/1000000 = 2345234.52345/10000000 = 23452345.2345/100000000 = 234523452.345/1000000000 = 2345234523.45/10000000000 = 23452345234.5/100000000000 = 234523452345/1000000000000

Factor the polynomial expression 4x2 +9.
Yanka [14]

Answer:

Step-by-step explanation:

Factor it by first setting it equal to 0:

4x^2+9=0 Now subtract 9 from both sides:

4x^2=-9 Divide both sides by 4:

x^2=-\frac{9}{4} Then take the square root of both sides:

x = ±\sqrt{-\frac{9}{4} } , which of course is not allowed. Therefore, we have to allow for the imaginary numbers in this solution. Knowing that,

x = ±\sqrt{-1*\frac{9}{4} } is an equivalent radicand, we can now replace -1 with its imaginary counterpart:

x = ±\sqrt{i^2*\frac{9}{4} }

Each one of the elements in the radicand are perfect squares, so we simplify as follows:

x = ±\frac{3}{2}i

And there you go!

What is the sum of x^2 - 3x + 7 and 3x^2 + 5x - 9
Dmitrij [34]

Hey there!

The answer to your question is 4x^2+2x-2

Given:

x^2-3x+7 and 3x^2 +5x-9

First, we can start by adding like terms. The following are like terms:

x^2 and 3x^2

-3x and 5x

7 and -9

Now, we can add these pairs together, giving us:

4x^2

2x

-2

Now, add all this together, and we get our answer as:

4x^2 + 2x - 2

Have a terrificly amazing day!
