I believe it’s
a = 4
b = -8
c = -3
Rate x time = distance
the distances are equal
x(30) = (x + 2)(20)
30x = 20x + 40
10x = 40
x = 4 mph
x + 2 = 6 mph
The distance is 2 miles
The missing side length is 7
Because the triangle is quadrupled so you divide 28 by 4
3.95 Because 3 5/6= 3.83 and 3 4/5 = 3.8
Q-1.8+1.8=14+1.8= Q=15.8 hope this helps
