Answer:
Step-by-step explanation:
area of rectangle=length×width
=(x²+6x+3)×(3x²+4x-2)
=3x^4+(4+18)x³+(-2+24+9)x²+(-12+12)x-6
=3x^4+22x³+31x²-6
Answer:
825/3 = 275 which is how many miles she drove in January.
275*4= 1100 which is how many miles she drove in February.
Ms. Turner drove 1100 miles in February.
Step-by-step explanation:
Answer:
Angle 9: 60°
Angle 10: 30°
Side = radius = 40sqrt(x/3)
Area = [800sqrt(3)]x
Step-by-step explanation:
Total angle in a hexagon:
(6 - 2) × 180
720
Each interior angle:
720/6 = 120
angle 9 = 120/2 = 60
Angle 10 = 60/2 = 30
sin(60) = 20sqrt(x)/r
r = 20sqrt(x) ÷ sqrt(3)/2
r = 40sqrt(x/3)
Side:
sin(30) = ½s/(40sqrt(x/3))
½s = 20sqrt(x/3)
s = 40sqrt(x/3)
Area = (3sqrt(3))/2 × s²
Area = 3sqrt(3)/2 × 1600x/3
Area = [800sqrt(3)]x
