Answer:
2y^2 +18x
Step-by-step explanation:
4y^2+6x-2y^2+12x
Combine like terms
4y^2-2y^2 +6x+12x
2y^2 +18x
The slope 3 is and the y-intercept is 6.
8.8 squared + 9.5 squared = square root 12.94 rounded 12.1
Work = force *distance
W= weight *height
W= (10kg) (9.8 N/kg)(2m) = 198 Joules
Hope this helps!
