if a storm windows has an area of 315 square inches, what are the dimensions if the window is 6 inches higher than it is wide (w x h)

Answers

Answer 1

Answer: Answer:
length of window = 21 in
width of window = 15 in

Explanation:
Assume that the width of the window is w
We are given that the length is 6 in longer than the width
This means that:
length of window = w + 6

Area of rectangle is calculated as follows:
area = width * length
area = w(w+6)
315 = w(w+6)
315 = w² + 6w
w² + 6w - 315 = 0
(w-15)(w+21) = 0

This means that:
either w-15=0 .......> w = 15 in .......> accepted solution
or w+21 = 0 .........> w = -21 in .......> rejected as width of window cannot be negative

Now, we know that:
length = width + 6
length = 15 + 6
length = 21 in

Based on the above calculations:
length of window = 21 in
width of window = 15 in

Hope this helps :)

Answer 2

Answer: $hw=315\n h=w+6\n (w+6)w=315\n w^2+6w-315=0\n w^2+21w-15w-315=0\n w(w+21)-15(w+21)=0\n (w-15)(w+21)=0\n w=15 \vee w=-21\n\n h=15+6=21\n\n\ w=15 \ in\n h=21\ in\n$

The quotient of 0 and -350 is zero.

The quotient of 276 and -8 is negative.

Step-by-step explanation:

The signs of the quotients are as follows:

-125 / 5 = -25, which is negative.

-264 / -12 = 22, which is positive.

0 / -350 = 0, which is zero.

276 / -8 = -34.5, which is negative.

Dr. Hunt just got his PhD, and he wants to print copies of his thesis in hardcover book format. He could use Wildgrove Printing, paying a setup fee of $38 and $6 for every book printed. Alternately, he could go through Salem University, paying an up-front fee of $36 and $7 per book. It turns out that, given the number of books Dr. Hunt wants to print, the two options cost the same amount. How many books is that? What is the amount?
