Answer:

D

Step-by-step explanation:

The formula of a circle is (x-h)^{2}+(y-k)^{2}=r^{2} where the vertex is (h,k).

The vertex is (4,-2) and the radius is 5, so substitute the numbers in and you get the solution.

. A square picture frame occupies an area of 112 ft2 . What is the length of each side of the picture in simplified radical form
saw5 [17]
Recall that a square is just a rectangle with all sides equal.

and the area of a rectangle is just length * width.

\bf \textit{area of a rectangle}\\\\
A=length\cdot width\quad 
\begin{cases}
length=x\\
width=x\\
A=112
\end{cases}\implies 112=x\cdot x\implies 112=x^2
\\\\\\
\sqrt{112}=x\implies \sqrt{16\cdot 7}=x\implies \sqrt{4^2\cdot 7}=x\implies 4\sqrt{7}=x

Simplify the expression. 7 √x • 7 √x • 7 √x
blsea [12.9K]
Answer:

√7x−49√x

Explanation:

First of all, expand by multiplying √7x⋅√x and √7x⋅7√7respectively:

√7x(√x−7√7)=√7x⋅√x−√7x⋅7√7

... you can express √7x as √7⋅√x...

=√7⋅√x⋅√x−√7⋅√x⋅7⋅√7

=√7⋅(√x)2−(√7)2⋅√x⋅7

... the operations squaring and taking the square root "eliminate each other"...

=√7⋅x−7⋅√x⋅7

=√7x−49√x

Hope that this helped!
