The answer is 4x^3+12x^2-5x-1
Answer:
120° = CAB
arc lenght = CÁB/ 360 × 2(pi)(4)
a/2pi(4) = CAB/360
8/3(pi)/2(pi)(4) × 360 = CÁB
120 = CAB
Answer:
x=65
Angle 1=65
Angle 2=115
Step-by-step explanation:
We know that angle 1 + angle 2 = 180. Writing it in terms of x, we get x + (x + 50)= 180. Then you have 2x+50=180. Subtracting 50 from both sides gives you 2x=130. Dividing both sides by 2, you get x=65. Angle 1 is 65 degrees. 180-65=115.
SA=2(LW+LH+WH)
if all are trippled then
SA=2(3L3W+3L3H+3W3H)
SA=2(9LW+9LH+9WH)
SA=2(9)(LW+WH+WH)
SA=9(2(LW+WH+WH))
the SA will be multiplied by 9
150 times 9=1350

Answer:
D'(1, - 1 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply the coordinates of D by 
, that is
D(2, - 2 ) → D'( (2) , (- 2) ) → D'(1, - 1 )
