Answer:
8
Step-by-step explanation:
8 + 7 = 15
15 ÷ 3 = 5
Use the formula or complete the square.
The zeroes of the quadratic can be real and rational; real and irrational; complex conjugates.
If the quadratic is ax²+bx+c, x=(-b+√b²-4ac)/2a.
If b² > 4ac the solutions are real. If b²-4ac is a perfect square, the solutions are real and rational; otherwise they’re real but irrational.
If b² < 4ac the solutions are complex.
Answer:
887 and 792 km per hour
Step-by-step explanation:
Lets call the first plane A and the second B
we know that: a=b+95
We can say that 3358=2b+(2b+190)<=A
When solved, we get 3168=4b
b=792 km per hour.
Go back to step two. A=b+95, so A=792+95=887 km per hour
The two planes rates are 887 km per hour and 792 km per hour.
Answer:
Answer:
Step-by-step explanation:
Since the product of the intersecting chords should be equal
==> AM x BM = CM x DM
==> 4 x 5 = CM x DM
==> 20 = CM x DM
Therefore CM x DM = 2 X 10
