First you want to subtract 36
so it looks like this ![\sqrt[4] {(4x+164)^3}=64](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%20%7B%284x%2B164%29%5E3%7D%3D64)
Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)
which is equal to 
Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]
Then you end up with the equation 4x+164=256
Then subtract 164 to both sides
4x=92
then divide 92 by 4
Then you get x=23
Bca is the answer, i need 20 letters in this to answer
Answer:
The correct option is (A).
Step-by-step explanation:
The expression Carey is solving is:
Simplify the expression as follows:
So, in Carey's calculation the third step is incorrect.
Instead of 27 the three-fourth must be multiplied by 36 to get the correct answer.
Thus, the correct option is (A).
Answer:
3/4.
Step-by-step explanation:
36 and 48 have a common factor of 12.
(36 / 12) / (48 / 12)
= 3/4 (answer).
For this question, we can use proportional reasoning to find out the answer.
Let us call the point at the other end of line and in between the two expressions, D.
Side AB:AC = BD:DC (remember that ratios are the same as division so you can do the exact same thing with division statements instead).
Now substitute: 8:12 = (x+4):(2x+1).
Now solve (if using division instead of ratios, solve regularily for x):
8:12 = (x+4):(2x+1),
8(2x+1) = 12(x+4),
16x+8 = 12x+48,
16x-12x = 48-8,
4x = 40,
x = 10.
Therefore x = 10
