First, we want to find the GCF of 15 and 21, which is 3. Now we do 15 divided by 3 and 21 divided by 3, which gives us 5 and 7. To rewrite the expression, we take the GCF and put it on the outside of the parenthesis. Inside the parenthesis, we put 5 + 7. So it'll look like this:
3(5 + 7)

14 over 4509 would be an equvilent fraction
Hello!
You can break this down
If she added 8 to the number
x + 8
Multiplied the sum by 2
2(x + 8)
it would equal 6
2(x + 8) = 6
The answer is B
Hope this helps!
You have to use Pythagoras' theorem for this!
The triangle formed is 6 units across, and 8 units down, which means we can form an equation like this:
a^2 + b^2 = c^2
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
c = 10.
The answer is 10 :)
