Im not sure but i think its A because you have no value to multiply 3 so you just multiply it by itself.It would be a negative because you cant divide 3 by 2.so it would be A.-x9y2.
i hope i was correct and helped if not you can go ahead and delete my answer:)

Find the geometric mean of 2 and 3
Sav [38]
The first step in solving this problem is taking 2 and 3 and multiplying them (2 * 3 = 6) .
Now, for the second step, we will cube it. Since there are 2 numbers, we are going to use the 2nd root (2sqrt(6)) This will give us: 4.89897948557 or 5 if you would round it. This would be the Geometric Mean.

Find the unknown side length
Westkost [7]
For any right triangle, we can use the Pythagorean Theorem. The Pythagorean Theorem states that for any right triangle, the legs when squared and added together will be equal to the hypotenuse squared.

In mathematical notation: a^2 + b^2 = c^2

Where the variables a and b are the legs and the variable c is the hypotenuse.

Because we know the two side lengths of the triangle, we can solve for the unknown side.

We know the length of one of the legs and the hypotenuse.

Plug in the values.

10^2 + b^2 = 24^2 \\ \\ 
100 + b^2 = 576 \\ \\ 
b^2 = 476 \\ \\ 


b = \sqrt{476}

So, the square root of 476 is the unknown length.

E is the midpoint of DF, DE = 2x + 4, and EF = 3x + 1. Find DE, EF, and DF.
Agata [3.3K]
When there is a midpoint in a line segment, the two segments that are then produced have to be equal. So that means that because E is a midpoint of DF, DE=EF.
Set up the equation.
DE=EF
2x+4=3x+1
Then solve for x.
x=3
Then plug it back in the equation to find DE and EF.
DE=2x+4=2(3)+4=10
Because DE=EF then EF is also 10.
DF is made from the addition of DE and EF so DF is twice EF.
DF= 20

DE= 10, EF= 10, DF= 20

Hope this helps.

Eurostar is a high-speed railway service connecting
Setler79 [48]

Answer:

649 trains

Step-by-step explanation:

If there are 30 seats per carriage, and there is 18 carriages per train.

You multiple 30 and 18 to get how many seats there are in a train.

30*18 is 540 seats.

To figure out how many trains would be needed to seat 350,000 passenger, you have to divide 350,000 with 540 to get how many trains would be needed.

350,000/540 is 648.1

Since the answer is 648.1 and you can't chop a train into 10 pieces, you would need 649 trains to seat 350, 000 passengers.
