The answer is the second one (B.)
Let number of miles be x
<span>when is </span>
<span>.5x + 25 = .25x + 30 </span>
<span>times 4 </span>
<span>2x + 100 = x + 120 </span>
<span>x = 20 </span>
<span>4 the square root of 2 + 7 the square root of 2 - 3 the square root of 2
= 4</span>√2 + 7√2 - 3√2
= √2(4 + 7 - 3)
= √2 (8)
= 8√2
Answer
8√2
Answer:
Step-by-step explanation:
In the question, we're given that the notation produces a number less than the product of and raised to the power. Let the number produced be . As a mathematical equation, we can write this production as
For , we can assign:
Substituting these values into , we get:
Add 2 to both sides:
Take the square root of both sides:
For , there are two cases:
Therefore, we have:
The only answer choice applicable is .
