Let's replace every copy of x with 7 and simplify.
Which is clearly false. This is probably the set of steps you followed to get "no solution".
Why is there no solution? Well let's subtract 9 from both sides to isolate the square root
Recall that the result of a square root operation is never negative. The range of 
and 
is the set of nonnegative numbers. There is no way we can have the left hand side result in -6
If there was a negative sign out front the square root and we have this instead
then the answer would be x = 7
Unfortunately, there isn't such a negative sign, so we stick with "no solutions".
Answer: B
Step-by-step explanation:
Answer:
The answer is no, it cannot be 11 inches
Step-by-step explanation:
If the width is 5 inches and the area must be less than 55 square inches,
5 x 11 = 55
55 = 55
It is asking if
55 < 55
The rate of the current is 2.03 mph if the small motorboat travels 8mph in still water. It takes 3 hours longer to travel 44 miles going upstream than it does going downstream.
<h3>What is a quadratic equation?</h3>
Any equation of the form 
Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
Let's suppose the rate of the current = r
The time it takes to go downstream + 4 hours = time to go upstream
As we know the:
Now,
After solving:
After cross multiplication
44(8+r) - 44(8-r) = 3(8+r)(8-r)
88r = 3(64 - r²)
3r² + 88r - 192 = 0
After solving the above quadratic equation, we get:
r = 2.03 or
r=−31.37 (reject as it is negative)
So, the r =2.03 mph
Thus, the rate of the current is 2.03 mph if the small motorboat travels 8mph in still water. It takes 3 hours longer to travel 44 miles going upstream than it does going downstream.

after 2 years. Because 4.25 is equal to .0425 then times that by the number.
