What is the solution of (4x-16)^1/2=36? please need help.
2 answers:
Answer: x=328
Explanation
in the given equation we will first remove the square root from the equation in order to do the same
From squaring both sides we get
4x-16 =
4x -16 = 1296
After shifting 16 on Right hand side we will get the following
4x= 1296 + 16
after adding right hand side we will get the following
4x = 1312
4 will shift to the right hand side we will get the following result
x =
finally after division by 4 we will get the final value
x =328

Answer:
C, 20 units
Step-by-step explanation:
We see that both angles QRS and QTR are 90 degrees. In addition, angles SQR and RQT are equivalent (because they're both angle Q).
By AA Similarity, we know that triangle QTR is similar to triangle QRS.
With this similarity in mind, we can look at the ratios of corresponding lengths to set up a proportion. QR from triangle QTR is the hypotenuse, and it corresponds to hypotenuse QS from triangle QRS. So, we can write the ratio x/(9 + 16) = x/25.
Now, we see that long leg QT of triangle QTR corresponds to long leg QR of triangle QRS. So, another ratio we can write is: 16/x.
Finally, we set these two ratios equal to each other:
Cross-multiplying, we get: .
Thus, x = . The answer is C, 20 units.
Hope this helps!

Step-by-step explanation:
Euclide's theorem states that in a right triangle, the square built of the side lenght is equivalent of the rectangle with sides hypotenuse and projection of the same side lenght. In formula, given the measures on the triangle:
