Step-by-step explanation:
# red marbles = 25
# blue marbles = 7
r + b = 32
r = 4 + 3b
substitute '4 + 3b' for 'r' in the 1st equation
4 + 3b + b = 32
4 + 4b = 32
4b = 28
b = 7
red = 32 - 7
r = 25
The Answer is B 8+ 6=14
14-8=6
8+6=14
14-6=8
<u>Use tangent:</u>
LABC is a 30°angle point B is at (3,2)
