Answer:
Step-by-step explanation:
an=an-1+(-4)
a2 = a1 + (-4) = 50 - 4 = 46
a3 = a2 - 4 = 46 - 4 = 42
a4 = a3 - 4 = 42 - 4 = 38
a5 = a4 - 4 = 38 - 4 = 34
Answer:
The Roman numerals CIX equals to 109.
The equation of a circle is:

Where (xc,yc) are the coordinates of the center.
Center (5, -5)
Radius = 3
(x-5)²+(y+5)²=3²
x²-10x+25+y²+10y+25=9
x²+y²-10x+10y+41=0
Answer:
84 cm^2
Step-by-step explanation:
Area of triangle + area of rectangle
Area of triangle = 1/2*l*b
= 1/2*8*3= 12 cm^2
Area of rectangle = l*b
= 12*6 = 72 cm^2
Total area= 72+12
= 84 cm^2
