Answer:
Step-by-step explanation:
The easiest way is to use a graphing tool and solve it graphically.
We did it with Desmos and it shows 3 real roots, see below.
The polynomial is of degree 7, hence it should have 7 roots.
Since there are 3 real roots, the remaining ones are complex, so there are 4 complex roots
Answer:
13/21
Step-by-step explanation:
Make 6 1/2 and 10 1/2 and improper fraction
6 1/2=13/2
10 1/2=21/2
K.C.F
Keep 13/2
Change the division symbol to multiplication
Flip 21/2 to 2/21
then multiply across
13*2=26
21*2=42
so the fraction is 26/42 and then simplify the fraction
13/21
As 1 mm = 0.01 dm
3.5 mm = 0.01*3.5 = 0.035 decimeter
