Answer:
D
Step-by-step explanation:
c = √(a² + b²) is correct because to isolate c you need to square root everything while still keeping a^2+b^2 together.

Step-by-step explanation:
Answer:
slope = - 44
Step-by-step explanation:
the derivative of f(x) at x = 3 is the slope of the tangent line
f(x) = -6x² - 8x + 5
differentiate using the power rule
f'(x) = - 12x - 8
f'(3) = - 36 - 8 = - 44 ← slope of tangent line at (3, 4 )
