You can figure this out if you just look at (x+a)^2 = x^2 + 2ax + a^2. See, the constant term, a^2, is the coefficient of x (2a), divided by 2 (2a/2=a), and then squared (a^2) 

<span>So you equation has 8x. 8/2 = 4, and 4^2 = 16. So the answer is A.</span>

Can you help me plz with 1,2,3,5,6 I'm not in this grade so plz help me
Elina [12.6K]
It looks like for all of these we will be using the Pythagorean theorem.

If you don't know what this is or how to apply it, go to the website "Khan Academy" and watch his video(s) on it. I would suggest going to that site whenever you don't understand something in math :)

I'll just be giving you the answers and won't explain what I'm doing, but please do go to Khan Academy to find out how to do it on your own!!

Anyway, onto the answers.

1) a = 12.5, b = 5.7, c = 13.7.
2) 24
3) 19.2
4) 6.4
5) 18.7
6) 98.5
7) 1.9

Hope this helps!!!

Given that (12,3) is on the graph of f(x), find the corresponding point for the function 8f(x)
Paha777 [63]
When the function is multiplied by a number, in this case f(x) is being multiplied by 8, the outcome of the function is multiplied by 8. So, if you were to still input 12 as x, you would get an output that is 8 times the original. 3 • 8 = 24. The new point would be (12, 24).
