Answer:
Step-by-step explanation:
If m is odd, that means the graph crosses the x-axis at x=a, if m is even, that means the graph touches the x-axis at x=a. x = a . The end-behavior of a polynomial function is given by the dominant term, anxn, a n x n , limx→±∞f(x)=limx→±∞anxn. lim x → ± ∞ f ( x ) = lim x → ± ∞ a n x n . HERE HOPE THIS WORK.
Answer/Step-by-step explanation:
Area of trapezium = ½*(AD + BC)*AB
Area = 42 cm²
AD = (x + 8) cm
BC = (x + 5) cm
AB = x cm
Plug in the values into the equation
42 = ½((x + 8) + (x + 5))*x
42 = ½((x + 8 + x + 5)*x
42 = ½(2x + 13)*x
Multiply both sides by 2
42*2 = (2x + 13)*x
84 = 2x² + 13x
2x² + 13x = 84
Subtract both sides by 84
2x² + 13x - 84 = 0
