Answer:
The hour hand of a clock moves -66* in 2 1/5 hours.
Step-by-step explanation:
2 x -30 = -60, and 1/5 of -30 is -6, and -60-6=-66 degrees.
Answer:
Step-by-step explanation:
6x = 3(x + 4) [Given]
6x = 3x + 12 [Distributive]
3x = 12 [Subtraction Property of Equality]
x = 4 [Division Property of Equality]

Answer:
Step-by-step explanation:
x^2+8x-3=0 (move constant to other side by adding 3 to each side)
x^2+8x=3 (halve thr linear coefficient, square it and add to each side, (8/2)^2=16)
x^2+8x+16=3+16 (now the left side is a perfect square)
(x+4)^2=19 (now take the square root of each side)
x+4=+-(19^(1/2)) (finally subtract the constant to isolate x by itself)
x= -4+-(19^(1/2))
x=negative four plus or minus the square root of nineteen
