Part A x^2-3x -4
Part B x^2 +3x -4
Party C x^2+x-20
Part D x^2-x-20
Answer:
I think the answer is x-11x^5+12x
Step-by-step explanation:
with reference angle E
perpendicular (p) = e
base(b) = g
hypotenuse (h) = f
so Now
Sin E
= p/h
= e/f
Answer:
Perimeter you add up all the sides. If it is a horizontal or vertical line, you just write those values for the side lengths. For the slanted one, I would use pythagorean theorem to solve it.
Step-by-step explanation:
If we make a right triangle using vertical and horizontal lines. We will find that a = 6, and b = 12. Find the square root of the sum of a squared plus b squared. That will tell you C. Then add C to the other 3 sides and that will give you the perimeter.
0.319 rounded to the nearest hundredths is 0.32. Because 9 is over 5 which makes it round up.
