======================================================
Work Shown:
Those are the possible solutions, but plugging x = -14 back into the original equation will lead to an error. So we rule x = -14 out
x = 6 works as a solution however
50 = x^2
To isolate x you need to do the opposite of an exponent, which would be square root.
= x
That is the exact form, in other words your answer, if teacher is looking for a decimal, it would be
7.07 = x
Answer:
Hence the area of CD bought by Nathan is <em>22.2784 square inches.</em>
Step-by-step explanation:
The length and width of a CD bought by Nathan is inches.
As CD have the same length and width this means it will be of the shape of a square.
Hence, the area of CD is given by:
Area of CD=length×width
=
=
=
=
=
Hence the area of CD bought by Nathan is 22.2784 square inches.
