First you need to find out how much he spends on each session.
0.15 is the answer.
Given the polynomial equation x^3 -6x = 3x^2 – 8. Which can be simplified into (x^3) -3(x^2) -6x +8 = 0. The roots of the given equation are x = -2, x = 1 and x = 4. The order of equation also represents the number of roots of the equation given. Since the highest exponent is 3, there also 3 roots. So the answer is D. 2 –2, 1, 4
Answer:
121

Answer:
Step-by-step explanation:
<u>8.</u> The angles are equal, so:
(2x+2) = (3x - 63)
-x = -61
x = 61
Angle (2x+2) is 124°
Angle (3x-63) is 120°
<u>9.</u> The sum of all angles in a triangle is 180°.
The sum of the two unknown angles is 90° [180° - 90° from the right angle°]
(8x+2) + (9x+3) = 90°
17x + 5 = 90°
17x = 85°
x = 5
The two angles are:
(8x+2) = 42°
(9x+3) = 48°
