You could do all of the work with the multiplying, but what I think it wants you to see is that you can divide like numbers by subtracting exponents.

so if we did that we would get $(-2^{2})(-3^3)(-5^1)$

this in turn would give us 4 x -9 x -5 = 180

The distance between (0,-4) and (2,-5)

alex41 [277]

Step-by-step explanation:

d= $\sqrt{ (0-2)^2 + (-4-(-5))^2}$

d= $\sqrt{(-2)^2 + (1)^2}$

d= $\sqrt{4 + 1}$

d= $\sqrt{5}$

In brianna's homeroom class, 9% of the students were born in march and 40% of the students have a blood type of o+.

Firlakuza [10]

Answer:

3.6%

Step-by-step explanation:

Because the two events are independent, their probabilities are multiplied, so the probability of a student being born in March and having a blood type of O+ is 9% * 40% = 0.09 * 0.40 = 0.036 = 3.6%

Solve for x.<br> Worth 20 pts.

Vinvika [58]

You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10
