You have to factor this...
So you have started with this...
x²-x-2=0
If you factor this you will get
(x+1)(x-2)=0
This gives you two solutions...
x=-1, x=2
Hope this helps! Give me a five-rate and a thanks!
It's a linear function with a slope 0.
It's a horizontal line (look at the picture).
Answer:
1875
Step-by-step explanation:
3x5 = 15

1875 because at the end of the next week, which basically turns 8 weeks into 4, and the number of contaminants multiply by 5 each other week.
I hope this helps.
When the circumference is divided by the diameter, the result can go beyond 100,000 decimal points, so to make calculations easier, pi is rounded to 3.14, or shown as the symbol π. Pi helps you calculate the area of the circle. ... Lenart says pi is useful in many fields that use math.
Answer:
Step-by-step explanation:
It is a right triangle, so use the Pythagorean Theorem to solve for x.
x² + 8² = 11²
x² = 11² - 8² = 57
x = √57
