Maybe search up Algebra calculator and type in the equation? idk
Answer: 20
explanation: simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers
Step-by-step explanation:
as x intercepts are -8 and 72 we realize that f(x)=a(x+8)(x-72)
we know that f(62)=-490 so a= -0.7
so f(x)= -0.7(x+8)(x-72)
Commutative Property.
It cannot be multiplication property because it would have to be live 5 x 1 = 5. For multiplication property the answer has to be the same as the number you used to get the answer. Does that make sense? I can send you a pic if you need it. I might be wrong because I just learned it now so I could give you an answer but from the example I got it has to be like 25x1=25, 100x1=100 something like that
