Answer:
32 seat covers
Step-by-step explanation:
All his expenses add up to $877. Divide 877 by 28 and you end up with 31.32. So he would need to sell at least 32 seat covers the cover all his expenses.

We know that the shortest leg of the largest right triangle (hypotenuse length 16) has a length of the square root of (y^2 + 16) through the pythagoras theorem. We also know that x is equal to the square root of (144 + y^2) as well. Finally, we know that 256 = (y^2 + 16) + (y^2 + 144), since we use the pythagoras theorem one last time and square each of the values we have got for the two legs of the largest right triangle. Therefore, 256 = 2y^2 + 160, 96 = 2y^2, 48 = y^2, y= sqrt48 = 4sqrt3 =
.
Intercept ⇒ when f(x) = 0
f(x) = 3x² - 12x - 1
3x² - 12x - 1 = 0
Answer: The two x-intercepts are (4.08, 0) and (-0.08, 0)
Carl is right because simplifying it gets us:
