Help me find the equation for the dimensions of a window, please!

On the sheet, it's not even asking you for the dimensions.
It's just asking you to set up the <em>equation that you would use</em>
to find the dimensions.  That's a great way to do it, because
nobody actually needs the answers, the whole thing is only
meant to help you learn HOW to find them.
==========================================
Call the width of the window 'W' .

We know that the length is 5 feet more than the width, so the length is (W + 5).

The area is (length times width).

Area = (W + 5) times (W).

36 = (W + 5) W

36 = W² + 5W

Subtract 36 from each side:

W² + 5W - 36 = 0

That's choice-4 .

Gang charges $22.50 per hour for Consulting Services how much was she charged for seven and a half hours of Consulting
Bogdan [553]

Answer

$168.75

Step-by-step explanation:

$22.50 per hour meaning every hour she gets 22.50

half an hour would be half the money so

22.50 * 7 = 157.50

22.50/2 = 11.25


157.50 + 11.25 = 168.75


168.75 is the answer
