Step-by-step explanation:
The first set is equivalent.
We obtain the right-hand side by swapping places of the terms.
So hmm check the picture below
and since you already covered solving system of equations, surely you'll breeze right through B)
The perimeter of the square is:
ft
Step-by-step explanation:
The picture is attached with the answer.
the diagonal of a square divides it into two right angled-triangles.
We can use one of the triangle to find the length of side as the diagonal will be the hypotenuse of the triangle
Let a be the side of the square, then according to Pythagoras theorem

Dividing both sides by 2

Taking Square root on both sides

Now,

Hence,
The perimeter of the square is:
ft
