Answer:

2^18

Step-by-step explanation:

2^2

------ * 2^8

2^-8

We know a^b * a^c = a^(b+c)

2^2 * 2^8 = 2^(2+8) = 2^10

2^10

-------

2^-8

a^b / a^c = a^(b- c)

2^(10 - -8) = 2^(10+8) = 2^18

Answer:

x = 4.25

Step-by-step explanation:

1. distribue the -5 on the left side of the equal sign by multiplying it with 2x and -9 inside the brackets. Do the same with the negative sign and the -6x and 10 in the brackets on the right side of the equation. this should make:

17 - 10x + 45 = 6x - 10 + 4

2. Combine like terms on both sides of the equal sign. Add 17 and 45, and add -10 and 4 to make:

62 - 10x = 6x - 6

3. Bring like terms onto the same side. You can either bring the 62 to -6, which would make 62 negative, or bring -6 to 62, making the 6 positive. Do the same with -10x and 6x. It should make:

68 = 16x OR -68 = -16x

4. Divide both sides by 16 or -16, depending on which option you went with.

68/16 = 16x/16 OR -68/-16 = -16x/-16

This gives:

4.25 = x

Indicate the method you would use to prove the two triangle 's . If no method applies, enter "none".

Sever21 [200]

You would use AAS because of the fact that there is two angles and the angle where both triangles instersect and create a verticle angle, there is no angle written. It has an angle then another angle then a side. Hope this helps!
