Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
Each person rode 2.9 miles and A total of 8 ones and 7 tenths are shaded to model the total length of the race. The shading is equally divided into 3 groups to model the 3 riders. And each group has 2 ones and 9 tenths shaded to model the distance each person rode
Y + 5 = 0
y >= -5
Therefore, you would choose the first answer.
Distance = rate x time
D = 450 mph x 2.5 h
D = 1,125 miles
