<span>((x+deltaX)^2+x+deltaX-(x^2+x))/deltaX = (x^2 + 2x delta x + (delta x)^2 + x + delta x - x^2 - x) / delta x = delta x (2x + delta x + 1) / delta x = 2x + delta x + 1
Therefore, </span>Lim as x tends to 0 of <span>((x + delta X)^2 + x + deltaX - (x^2 + x)) / deltaX</span> = 1 + delta x
Sorry I don't know I'm not that good at these kinds of things so so so sorry

Answer:
135°
Step-by-step explanation:
To convert from radian measure to degree measure
degree measure = radian measure ×
, so
degree =
× 
Cancel π on numerator/denominator and 4, 180 by 4, leaving
degree = 3 × 45 = 135°

Answer:
y = 0
Step-by-step explanation:
Subtracting the right side gives ...

The factor multiplying y cannot be zero, so y must be zero.
