What are the numbers that are supposed to be plugged in?
I don't really know what you're trying to ask because
x = -2 and x=6 are your roots.
But if you want to convert them back to their equation form,
get the other side of the equation to be 0.
x = 6
x - 6 = 0
x = -2
x + 2 = 0
so your original equation had something like (x+2)(x-6)
to get from 15 to 12 you subtract 3
to get from 12 to 17 you add 5
to get from 17 to 14 you subtract 3
to get from 14 to 19 you add 5
so, based on this pattern you can assume that you can get the next number by subtracting 3 from 19. so that means you'd do 19-3 and you would get 16 as your answer.
your answer is C.16
Hope this helps :)
Answer: B
Step-by-step explanation:
radical
√7(√14 +3√7)
using distributive property,
√7√14 +3√7√7
we can write √14 as √2*√7,
√7√2√7 +3√7√7
√7(√14 +3√7)=7√2 +21
