Answer:
2 times the shortest leg (leg oppo. the 30 degree angle)
If P1 has coordinates (x1, y1) and P2 has coordinates (x2, y2), then the distance between the two points is given by [(x1 - x2)2 + (y1 - y2)2]½ or [(x2 - x1)2 + (y2 - y1)2]½ Using the same two points as above, the midpoint formula is M = [(x1 + x2)/2], [(y1 + y2)/2] If we wanted to find the slope of the line on which the two points lie, it would be given by: m = (y1 - y2)/(x1 - x2) or (y2 - y1)/(x2 - x1) Some quadratic equations can be easily factored, some cannot. For those cases we use the Quadratic Formula: If ax2 + bx + c = 0 then x = [-b ± (b2 - 4ac)½]/2a Notice that the Distance, Midpoint and Slope Formulas all refer to linear equations. The quadratic formula, as the name implies, is used to find roots of an equation in which the variable x is squared.
True.. it should be from what i read about it on other sites.
Answer:
x=-28
Step-by-step explanation:
you multiply the number first
and you calculate
then you move constant to the right
you changes the sign
done!
