Do you mean that the length of the side going up is 8 units and the length of the side going to the right is 8 units?

If that is the case and the shape you have is a rectangle, then the are is just base times height.

The base is 6 and the height is 8.

6 times 8 is 48. So the area is 48 square units.

I can observe that 1 dorito plus 2 doritos equals 3 doritos. 1 dorito plus 2 doritos will always be 3 doritos. Is math really unobservable? If math was not observable, 1 dorito plus 2 doritos might equal 3 doritos sometimes but other times it might not. ^-c^

7 + (1/2)b = 10b

7 + 0.5b = 10b

7 = 10b - 0.5b

7 = 9.5b

7/9.5 = b

14/19 = b

I thought 0⁰ was undefined or something?

Multiplied out it's:

3(3x-4)² - 4

= 3(3x-4)(3x-4) - 4

= 3(9x²-24x+16) - 4

= 27x² - 72x + 48 - 4

= 27x² - 72x + 44

I got this by copying and pasting the number into the calculator on this website. :)

Because an apple a day keeps the doctor away. You don't ever hear people sayin how "A CD player a day keeps the doctor away," or how "A truck a day keeps the docor away," now do you? You don't. Exactly.

If your goal is to simplify, here's how:

9yx9y+yxy-8yx8y

= 81xy² + xy² - 64xy²

81 apples + 1 apple - 64 apples = 18 apples

81xy² + xy² - 64xy² = 18xy²

(12 + 144 + 20 + 3√4)/7 + 5(11) = 9²

(176 + 6)/7 + 55 = 81

182/7 + 55 = 81

26 + 55 = 81

81 = 81

Hey that's pretty cool! I didn't know what a "gross" was so I had to look that up. Learn somethin new every day! :)
