I need the picture to fully answer your question
dude.
Well, assuming that you need to round to the nearest whole number, what is six closer to? 0, or 10? The answer is 10. Therefore, you would round up to 33. Hope this helps!
Answer:
4..............21...........
X^2 - 9x + 18
factors of 18: 1*18, 2*9, 3*6,
the sums of the factors: 19, 11, 9
the positive 18 tells us both factors have the same sign, the negative 9 tells us they are both negative
(x - 3)(x - 6)
Parallel would be anything with the slope of 4x and perpendicular would be anything with the slope of 1/4
