Answer:
Discriminant = 93, two real roots/solutions
Step-by-step explanation:
Discriminant = b² - 4ac = (9)² - 4(3)(-1) = 81 + 12 = 93
Since 93>0, the quadratic equation has two real roots/solutions.
m=y+7x, or m=7x+y, it is correct either way you would write it.
The perimeter is the measure around the shape, so just add all the sides together-
6+5x+x+2
6x+8
Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2
6(x+2)
6x+12
/2
3x+6
Because the problem represents right angle we can use simple geometric functions to determine size of sides of triangle and its angles if needed.
Since we have angle at point that is 42 feets away from base of the building and we need lenght of side that is oposite from that angle that means that we need some trigonometric function that includes those 2 sides.
that function is tangens.
tan67 = oposite side/side next to angle
tan67 = x/42
x = 42*tan67
x = 98.94 feet
Answer is D 99 feet
