Answer:
One real root
Step-by-step explanation:
By the fundamental theorem of algebra, an nth degree polynomial has n-possible real roots.
If there are complex roots, then the the complex roots come in pairs.
Therefore the number of possible real roots of
are 3 real roots with no complex pairs or 1 real root with a complex pair.
By Descartes rule of signs, there is only one change of sign in the polynomial (+ to -).
Hence there is only one positive real root.

There is change is sign two times but we can not have even number of real roots for this polynomial
Therefore there is only real root.
Answer:
The volume is 878.625
Step-by-step explanation:
First you can convert the mixed numbers and fractions into decimals to make life so much easier. 4 1/2 = 4.5 and 71/4 =17.75
Then simply mulitply 4.5 x 11 x 17.75 and get 878.625
Solving:
1) Pass: Make the rule three (Directly proportional)
Two inch nails ______ grams (<span>Weight)
</span>15 ----------------------------35
n ----------------------------- 175
2) Pass: <span>Multiply cross
</span>

3) Pass: Simplify




Answer:
75 nails weigh 175 grams
