Answer:
Explanation:
A=l x w
You would set the formula up like this:
A = (x - 5)(x - 6)
To solve this you would distribute. Starting at the x in (x - 5), you multiply it by the x in the second pair of parentheses, giving you x^2. Then, multiply the first x by -6, which gives you -6x. Once you've multiplied that first x by everything in the second set of parentheses, you move on to the second term, -5. You now multiply -5 by x, giving you -5x. And lastly, multiply -5 by -6, giving you positive 30(two negatives make a positive).
At this point you have:
A = x^2 - 6x - 5x + 30
The next step is to add like terms, the only ones here being -6x and -5x, which gives you -11x:
A = x^2 - 11x + 30
Being your final answer
I hope this helps you :)
