Hi! I am confident that the answer is 230,000 because if country A is 10^3 times greater it would have to be 230,000,000 divided by 1,000 since 10^3=1,000. Hope this helps
here is the equation I used: A=10^3+B
2.5 miles per hour
Because 3/4 divided by 3/10 is equal to 2.5
Answer:
t=5.20s
Step-by-step explanation:
I think that is the expression because it say he purchases two bags, all the bags are 5.20 so he brought two bags which are school bag and one hand bag the formula I used was y=mx+b but in these case I had to put t=5.20x. I hope this really helped you..
If you mean "factor over the rational numbers", then this cannot be factored.
Here's why:
The given expression is in the form ax^2+bx+c. We have
a = 3
b = 19
c = 15
Computing the discriminant gives us
d = b^2 - 4ac
d = 19^2 - 4*3*15
d = 181
Note how this discriminant d value is not a perfect square
This directly leads to the original expression not factorable
We can say that the quadratic is prime
If you were to use the quadratic formula, then you should find that the equation 3x^2+19x+15 = 0 leads to two different roots such that each root is not a rational number. This is another path to show that the original quadratic cannot be factored over the rational numbers.
