It would be the second choice. This expression is a polynomial because it is multiple terms and is a degree of three because the largest exponent is three. So your answer is:
2y^3 + 5y^2 - 5y
Answer:
2x +5x-20+3x=180(angle of triangle)
10x-20=180
10x=180+20
10x=200
x=200/10
x=20
Answer:
Step-by-step explanation:
Area of sector = (∅/360°) x πr²
Area of sector = 48cm²
radius = 4cm
π = 3.14
48 = (∅/360°) x 3.14 x 4 x4
48 = (∅/360°) x 50.24
48/50.24 =(∅/360°)
0.9554 = (∅/360°)
∅ = 0.9554 x 360 = 343.949≈343.95° ( these is when the angle is in degrees)
if it is radians
area of sector = 1/2r²∅
area of sector = 48
r = radius = 4
area of sector = 1/2r²∅
48 = 1/2 x 4 x4 x∅
48 = 2x4 x∅
48 = 8∅
∅ = 48/8 = 6 radians
the central angle in radians is 6
Answer:50.27 centimeters
