Answer:
-5n²-8n+4
Step-by-step explanation:
Remove Parentheses :
3n²-5n+6 - 8n²-3n-2
Collect/Combine Like terms:
(3n²-8n²) + (-5n-3n) +(6-2)
Simplify:
-5n²-8n+4
Area of a triangle can be found using the equation base x height / 2
(5)(6)/2 = 30/2 = 15
The area of the triangle is 15mm
Step-by-step explanation:
Since we are told that 10 is a zero,
(x−10) must be a factor:
F(x)=2x3−14x2−56x−40
F(x)=(x−10) (2x2+6x+4)
F(x)=2(x−10)(x2+3x+2)
F(x)=2(x−10)(x+2)(x+1)
So the other two zeros are
x = -2 and x= −1
Usually first comes x the horizontal
then y the vertical
so the vertical distance is 8
Use the slope formula
M=y2-y1/x2-x1
M=5-3/10-8
M=2/2
M=1
