Rewrite each expression as a single logarithm. Then evaluate the expression without a calculator.
1.) log 5 + log 20
2.) log 3 – log 30
3.) 2 log 400 – log 16
PLS HELP OUT I WILL PAY 60 MORE POINTS IF YOU DO

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

Answer this question only if you know the 30 points and

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
