Answer:
y^2 + 4y + 3
Step-by-step explanation:
(y + 3)(y + 1)
(y*y) + (y*1) + (3*y) + (3*1)
y^2 + y + 3y + 3
y^2 + 4y + 3
Best of Luck!
Answer:
c
Step-by-step explanation:
Car A Car B
d=rt d = rt
d = ra * 2.4 d = rb 4
ra = rb+22
distances are the same so set the equations equal
ra * 2.4 =rb *4
substitue in for ra
(rb+22) 2.4 =rb *4
distribute
2.4 rb +52.8 = 4 rb
subtract 2.4 rb from each side
52.8 = 1.6 rb
33 = rb
Car b travels at 33 miles per hour
Car a = 33+22
Car a = 55 miles per hour
