you Need to think of 2 square numbers that add up to make 80

answer:

64 + 16

this means that x = 8 and y = 4

because of the square roots

or

y = 4

and

x = 8

Find f/g for the functions provided. 10 points Help needed.

-BARSIC- [3]

ANSWER

$( \frac{f}{g} )(x) = \frac{1}{3} ( {x}^{2} + 3x + 9)$

EXPLANATION

The given functions are

$f(x) = {x}^{3} - 27$

and

$g(x) = 3x - 9$

$( \frac{f}{g} )(x) = \frac{f(x)}{g(x)}$

$( \frac{f}{g} )(x) = \frac{ {x}^{3} - 27}{3x - 9}$

$( \frac{f}{g} )(x) = \frac{ (x - 3)( {x}^{2} + 3x + 9) }{3(x -3 )}$

Cancel the common factors,

$( \frac{f}{g} )(x) = \frac{ {x}^{2} + 3x + 9 }{3}$

OR

$( \frac{f}{g} )(x) = \frac{1}{3} ( {x}^{2} + 3x + 9)$

Answer: x=8

Step-by-step explanation:

the sum of the interior angles of a quadrilateral is 360 (number of sides-2 * 180)

so

$14x-7+11x-2+93+76= 360\\25x + 160=360\\25x= 200\\x=8$

JulijaS [17]

Answer:

So, when we solve for x we see that we can make 16 cookies using 1 cup of sugar. Then, yes, as you suggested we could divide 30 cookies by this ratio to see that we need less than 2 cups of sugar to make 30 cookies: And, as you said, this value is less than 2 cups, the value under Quantity B. Good job! I hope this helps :)
