2 is a common factor for both of them.
zavuch27 [327]3 years ago

They are 1 and 2, because the prime factorization of 20 is 2*2*5, and the prime factorization of 42 is 2*3*7. 
You can find the prime factorization of any number at this website, for future reference: http://www.calculatorsoup.com/calculators/math/prime-factors.php

I hope this helps you.

bonufazy [111]

Answer:

Lets say you have "100" apples.

If you lost 50% of those 100 apples, (50 apples) and then half of them went rotten, then no, it wouldn't be the same. But if you picked them all back up, and none of them were damaged, then yes, they would stay the original amount.

Solve this equation for x. Round your answer to<br> the nearest hundredth.<br> 1 = In(x + 4)
KATRIN_1 [288]

Answer:

x ≈ - 1.28

Step-by-step explanation:

Using the rule of logarithms

log_{b} x = n ⇔ x = b^{n}

Given

ln(x + 4) = 1 , then

x + 4 = e^{1} ( subtract 4 from both sides )

x = e^{1} - 4 = - 1.28 ( to the nearest hundredth )

I need help ASAP!!
Studentka2010 [4]

Answer:

  D.  (x-5)^2 = 36

Step-by-step explanation:

If you add 11 to the given equation, you get ...

  x^2 -10x = 11

Then you can add the square of half the x-coefficient to complete the square.

  x^2 -10x +25 = 11 +25

  (x -5)^2 = 36 . . . . simplify to the appropriate form

A student is asked to factor, if possible, the given expression. The student's response demonstrates which common misconception?
dlinn [17]

Answer:

The student assumed he was asked to factor

(a^2 - b^2)

Which is equal to

= (a+b)*(a-b)    (His response)

But, he was asked to simplify

(a^2 + b^2)

Which has imaginary roots, and can be factored as:

(b +ai)(b-ai)
