Answer:
Step-by-step explanation:
Consider polynomial
If x=-2 is its zero, then you can divide the polynomial by and get
If x=-1, then the polynomial can be rewritten as
The quadratic polynomial has roots
Then the polynomial has zeros
Answer: Yes, the answer 32 is correct.
Explanation: Since, According to the mid point theorem, the line segment connecting the midpoints of the two sides of a triangle is parallel to the third side and is half of the third side of triangle.
Here, FD is the line segment connecting to the midpoints F and D and it is parallel and half of the third side AC.
Thus, FD=AC/2⇒ AC=2FD
But, according to the question, FD=16 so, AC=2×16=32
Thus, AC=32 unit will be the answer.
Step-by-step explanation:
x^2+(x+9)^2=90
x^2+(x+9)^2-90=0
x^2+x^2+9^2+2*x*9-90=0
x^2+x^2+81+18x-90=0
2x^2+18x-9=0
Answer:
A.Pirate is more popular with students, but moose is more popular with teachers
Step-by-step explanation:
Its A because majority of students picked pirates and majority of teachers picked moose.
It's not B because the preferences are a lot different between students and teachers.
