Answer:
use the zero as an common multipal
Step-by-step explanation:
The diagonal of a square is equal to the side x times square root of 2, xSqrt(2)
z = xSqrt(2), its rate of change is just Sqrt(2)
Luke earned $54 for 3 lawns
So each lawn = $54/3 = $18
After mowing 7 lawns =
7 X $18 = $126
I think it is 50? (Sorry if im wrong tho.)
Relative extrema occur where the derivative is zero (at least for your polynomial function).
So taking the derivative we get
<span>20<span>x3</span>−3<span>x2</span>+6=0

This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>
