Answer:
Step-by-step explanation:
we know that
2 is a zero of multiplicity 3 of the polynomial
so
we have that
x=2 is a solution of the polynomial
A factor of the polynomial is
----> is elevated to the cube because is a multiplicity 3
and the other solution is x=-2
since the polynomial is fifth degree, x=-2 must have a multiplicity 2
so
the other factor of the polynomial is
----> is squared because is a multiplicity 2
therefore
The polynomial is equal to multiply the factors by the leading coefficient
so
Answer:
337.5 cm squared
Step-by-step explanation:
We are given the formula for the surface area of a cube: , where "a" is the length of each edge.
The problem says that the length of each edge is 7.5, so this is the value for "a" that we want to use. Substituting 7.5 in for "a", we have:
Thus, the total surface area is just 337.5 cm squared.
Hope this helps!
