Step-by-step explanation:
We have been given an expression
. We are asked to complete the square to make a perfect square trinomial. Then, write the result as a binomial squared.
We know that a perfect square trinomial is in form
.
To convert our given expression into perfect square trinomial, we need to add and subtract
from our given expression.
We can see that value of b is 11, so we need to add and subtract
to our expression as:

Upon comparing our expression with
, we can see that
,
and
.
Upon simplifying our expression, we will get:


Therefore, our perfect square would be
.
Answer : The answer is $153.00 from selling magazine subscriptions on Saturday.
Explanation : We know that each magazine is equal to $8.50. At first she sold 17 of the 35 magazines. 17 x $8.50 = $144.50 from selling 17 magazines. Now we do 35-17 to get how many magazines are left. So there is 18 magazines left. We need to do the same thing we did before, 18 x $8.50 = $153.00. She got $153.00 from selling 18 magazines on Saturday.
