Answer:
A. x^2 + 3x - 10 = 0
Step-by-step explanation:
If 2 and -5 are the solutions of the equation then
x - 2 = 0 and x + 5 = 0
So equation will be:
(x - 2)(x + 5) = 0
Expand by using FOIL
x^2 + 5x - 2x - 10 = 0
x^2 + 3x - 10 = 0
Answer is A. x^2 + 3x - 10 = 0
Answer:
Circles
Step-by-step explanation:
Think of a soup can sitting on its base on a kitchen counter. The counter is an example of a plane (through) parallel to the base. The points where the can and counter intersect form a circle. Put a book on top of the can. Again, the plane of the book is parallel to the base and the book and can intersect in a circle.
The same thing would happen if you cut the can open with a plane anywhere in between the two mentioned above, but it would make a mess!
Answer:
m = 17.5
Step-by-step explanation:
Given 0.2m=3.5, we want to solve for m. This involves isolating m on the left side. To accomplish this, divide both sides by 0.2, obtaining:
m = 3.5/0.2, or m = 17.5
100,000,000 ÷ 100,000 = 1,000
1,000 days.
