Your answer is C) 2a² + 2b²
To find this we can just expand the brackets of (a - b)² and (a + b)², and then combine like terms:
(a - b)² = (a - b)(a - b) = a² - 2ab + b²
(a + b)² = (a + b)(a + b) = a² + 2ab + b²
Then when you combine like terms, you get (a² + a²) + (-2ab + 2ab) + (b² + b²), so the ab terms cancel out and you get left with 2a² + 2b².
I hope this helps!
5.3K+2-2=18.43-2
5.3K=16.43
5.3K/5.3=16.43/5.3
K=3.1
Answer:
![\boxed{12}](https://tex.z-dn.net/?f=%5Cboxed%7B12%7D)
Step-by-step explanation:
When x = 3, y = 13
When x = 5, y = 37
Subtract both y-values to find the change:
37 - 13 = 24
Average of the change:
= 12
Answer:
WX = 11
Step-by-step explanation:
We know that VX is the full line segment.
We also know that VX = 14.
There is a point W on the line segment.
From this we know that the length of VW = 3.
To solve for WX we have to figure out how much distance is in between W and X.
To do this we have to simply subtract 3 from 14.
14 - 3= 11
Thus, we know that WX = 11.
