Answer:
![4 \sqrt[3]{6x}^{2}](https://tex.z-dn.net/?f=4%20%5Csqrt%5B3%5D%7B6x%7D%5E%7B2%7D)
Step-by-step explanation:
a like radical just means one that's similar to the original. going through your options, you should look for one with the exact same contents in the brackets as the one asked in the question. in this case, we see it's the third one because the contents inside are the same. the outside value (or known as the stretch/compression value) doesn't change the fact that it is still like to the original.
5•1=5
5•2=10
5•3=15
5•4= 20
5•5=25
5•6=30
There are multiple more, just keep multiplying by a number higher than 4
Let "x" be the mystery number
A product of 4 and this number = 4x
Six less that that = subtracting six from 4x
So the final equation is
4x-6=5
P.S.: x = 2.75
Answer:
40 miles per hour
Step-by-step explanation:
Given that:
Distance = 400 miles
Without tailwind :
Time taken = 2.5 hours
Speed = distance / time
Speed = 400 miles / 2. 5
Speed = 160 miles per hour
With tail wind :
Time taken = 2 hours
Net speed = 160 + x
X. = speed of tail wind
Distance = speed * time
400 = (160 + x) * 2
400 = 320 + 2x
400 - 320 = 2x
80 = 2x
x = 40
Speed of tailwind = 40 miles per hour.
