f(g(x) ) = -2(3x²+5x+14) +10
= -3x²-10x- 28+10
= -3x²-10x -18
The rate would be the gradient which is dy/dx
so the answers are
4x and 5x
Step-by-step explanation:
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

Answer:
(x,y) = (6/5, 38)
Step-by-step explanation:
y = y right?
so, you just substitute both of those equations
26+10x = 44-5x
26 -44 = -5x -10x
x = 6/5
then substitute x into ANY of these two equations
let's say we want the second one
y = 44 - 5 × 6/5
y = 38
I'm not sure but I think that first number there might be a 20 and not a 26. If that's true then, solving the same way you'd have
(x,y) = (8/5, 36)
