This is prime factorization
we need to know what number might go into 63
Most people who know their times tables remember that 9 * 7 = 63
7 is a prime number so it would go into the circle, and the 9 will go into the box

9 isn't prime, but 3 * 3 = 9. 3 is a prime number so the 3's will go into the circles below the 9.

If you need a final answer you can write 63 = 3 * 3 * 7

You can get the same factors if you use 3 *21 instead of 9*7 at the beginning. I'll let you figure out that one.

Help please explain how?

Pani-rosa [81]

Starting from the half circle, the radius is 2, (from the other side of the figure) and using that, 2 x 2 = 4 x 3.14 (or pi) = 12.56. But, it's a half circle. So, 12.56 / 2 = 6.28.
One in the bag!
Going left, we have a rectangle. b x h = a. 6 x 8 = 48.
Done. (by the way, that's the enclosed space)
Finally, the triangle. The triangle's area is found by 1/2 x b x h. 1/2 x 2 x 6 = 6.

The full area of the figure is 60.28.

Hope this helped.

Let U = {1, 2, 3, 4, 5, 6, 7, 8}, A =

mr_godi [17]

The equivalent set will be <u>A U B = {1, 2, 4, 5, 6, 8}</u>

<h3>Set theory</h3>

Given the following sets

U = {1, 2, 3, 4, 5, 6, 7, 8},

A ={2, 4, 6},

B = {1, 2, 5, 8},C = {1, 3, 7}

Required sets

A U B

Since union means that we are to write out all the values in the set A and B, hence the equivalent set will be;

A U B = {1, 2, 4, 5, 6, 8}
