Just by the language difference means subtract,
Y^2-25 is the difference of squares
factored it's the sum and difference of their square roots
(x+5) (x-5)
With pythagorean theorem and working backwards, you do 8100-1225 to get 6875, you then get the square root of that to get x=82.91 or rounded to 82.92
To make a large batch of cinnamon rolls, the baker uses 12 cups of white flour and 10 cups of whole wheat flour. All together, he uses 176 ounces of flour. The baker uses 2 fewer cups of whole wheat flour than white flour.
The answer is d is less than 6
I'm guessing it is 18. 18 decreased by nine equals nine so to me it makes sense.
