Short answer x = 11/3
Step OneChange 64 to a power of 4
Step TwoInclude 2x - 4 as part of your power. So far you are only working on the right side of the problem.
Step Three
The bases are the same so you can equate the powers.
2x + 6 = 4(2x - 4)
Step FourRemove the brackets on the right.
2x + 6 = 8x - 16
Step fiveCollect like terms. Begin by adding 14 to both sides.
2x + 6 + 16 = 8x Subtract 2x from both sides.
22 = 8x - 2x
22 = 6x Divide by 6
22/6 = x
x = 3.666333 or 3 2/3 or 11/3
Check
Left hand side4^(2*11/3 + 6)
4^(22/3 + 6)
4^(22/3 + 18/3)
4^(40/3)
Right Side64^(2*11/3 - 4)
64^(22/3 - 4)
64^(22/3 - 12/3)
64^(10/3) There is something we can do without figuring out what this is.
64 = 4^4
4^(4*10/3)
4^(40/3) which is the same as the left side

Answer:
The orange goldfish is 25 inches long
Step-by-step explanation:
Sorry I hope my answer makes sense, his question was a lil hard to read
2 x 11 = 22 + 3= 25
-2x - 13 = -3x - 5
Step 1: Combine like terms
x's go with x's (-2x and -3x). To do this add 2x to both sides
(-2x + 2x) - 13 = (-3x + 2x) - 5
(0) - 13 = (-x) - 5
- 13 = -x - 5
normal numbers go with normal numbers ( -13 and -5). To do this add 5 to both sides
(- 13 + 5) = -x + (- 5 + 5)
-8 = -x + (0)
-8 = -x
Step 2: Isolate x by dividing -1 to both sides (this will take the negative sign away from the x)
8 = x
x= 8
Hope this helped!

- You have to use this equation:
(difference/original) x 100
Substitute the values in:
(200/1500) x 100 = 13.3333333
You may leave it in fraction form as 40/3 or write it as 13.33%
