Answer:
the perimeter is 152, the area is 910
Step-by-step explanation:
perimeter = 20+50+20+10+6+15+6+25
=152
area = (20×50)-(6×15)
= 1000-90
= 910

Answer:
The slope of the given line is -4
Step-by-step explanation:
The formula of the slope of a line passes through points (x1, y1) and (x2, y2) is m =
In the given figure
∵ The line passes through the points (-6, 5) and (-4, -3)
∴ x1 = -6 and y1 = 5
∴ x2 = -4 and y2 = -3
→ Substitute them in the formula of the slope above
∵ m =
∴ m =
∴ m =
∴ m = -4
∴ The slope of the given line is -4
The discriminant is b^2-4ac
In this equation 9=a, 12=b, 4=c
Plugging into the formula
12^2-4(9)(4)=
144-324 =
-180 is the discriminant
Since the discriminant is a negative number there are no real roots
