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.

1/4x +4 = 1/2 solve with explanation
IRINA_888 [86]

Answer:

<h3>x = -14</h3>

Step-by-step explanation:

Given the equation

1/4x +4 = 1/2

Solving for x

Subtract 4 from both sides

1/4x +4 - 4 = 1/2 - 4

1/4 x  = (1-8)/2

1/4 x = -7/2

Cross multiply

2x = -7*4

2x = -28

x = -28/2

x = -14

Hence the value of x is -14

What is area of this shape
german

Answer:

132 ft squared

Step-by-step explanation:

One way is to divide the shape into a rectangle and a triangle, by drawing a vertical line.

This gives a rectangle that is 9 by 11, so has area 99.

The triangle has a base of 11 and height of 15 - 9 = 6.

So the area of the triangle = 1/2 x b x h = 1/2 x 11 x 6 = 33

So the total area is 99 + 33 = 132.

Which statement is true
loris [4]

Answer:


Step-by-step explanation


You must find the common denominator for all of them.  


A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.


B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.


C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.


D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.
