Answer:
1.) x-7
Step-by-step explanation:
hope it helps
<span>Turn 1 3/4 into a decimal number: 1.75
So, 120 miles in 1.75 hours, but we want to know miles in *one* hour. Divide both numbers by 1.75. 120/1.75 miles in 1.75/1.75 hour = 120/1.75 miles in 1 hour. 120/1.75 is 68.57 miles in one hour, so 68.57 mph.</span>
The simplest radical form is
Explanation:
The expression is
To determine the radical form, let us write the number 68 as a product of prime factors.
Thus, we have,
Since, 2, 17 are prime factors and hence, no further factorization is possible.
Hence, it can be written as,
Applying the radical rule , we have,
Simplifying, we have,
Thus, the simplest radical form is
