X(x+3)-7(x+3)
x2+3x-7x-21
x^2-4x-21
5x+4 is your answer first you do distributive property then you and like terms
Answer:
Step-by-step explanation:
Area of a circle = πr^2
Area of a sector with angle x° = (x/360) πr^2
For the smaller sector,
x = 30°
r = 6 in
Required area of sector = (30/360) × π × 6^2 = 9.424 in^2
To the nearest hundreth, Area = 9.42 in^2
13.5 = 30% of 45
4.5 = 15% of 30
4.6 = 23% of 20
4.2 = 60% of 7
Hope this helps!!
