HELP PLEASE URGENT!!!
If you help with ONE at least I will CROWN BRAINLIEST

Answer:
7. y = 11x - 3.
Step-by-step explanation:
I've only got time to do one.
y = 3x^2 + 5x
slope = y' = 6x + 5
At the point (1, 8) the slope is 6(1) + 5 = 11.
The equation of the tangent :
y - 8 = 11(x - 1)
y - 8 = 11x - 11
y = 11x - 3.
