Answer:D
Step-by-step explanation:
Step-by-step explanation:
the triangle is an isosceles triangle hence the base angles are equal
sum of angles in a triangle is 180°, therefore, the top angle =180-(62+62)
the top angle =56°
h°= the top angle because alternate angles are equal
hence, h=56°
Add n on both sides:
3m = km - 8 + n
Subtract km on both sides:
3m - km = n - 8
Factor the Left-Hand Side:
m(3 - k) = n - 8
Divide both sides by (3 - k):
m = (n - 8) / (3 - k)
Answer:
(4, -6)
Step-by-step explanation:
(x1+x2)/2 + (y1+y2)/2 = midpoint
(11+-3)/2 = 8/2 = 4. x = 4
(-5 + -7)/2 = -12/2. y = -6
4, -6 is the midpoint

Answer: second option
Step-by-step explanation:
The standard form of a quadratic equation is:
Then, to write the quadratic equation given in the problem in standard form, you must substract 1 from both sides of the equation. Then you have:
Given the quadratic equation above, to find the value of 
you must substitute:
a=2; b=5 and c=-1 into
Thenrefore, you obtain the following result:
