Each square in the diagram is equal to the value of 1 while c isn't equal to the squares. Simply $1\neq c$ . Since there are 6 squares that means 1*6 = 6. The whole value of the squares is 6. While the rectangle value isn't known or defined as "c" and you have 3 rectangles the value of it would be 3*c which is 3c.

So the answer is <u>C. 6+3c</u>

A boat is traveling at 43.2 m/s. It then goes down a faster part of the river and is now going 144

Marina86 [1]

Answer:

Step-by-step explanation:

boat was at 43.2 m/s speed increase to 144 m/s

if the boat was moving 0 m/s and increased to 144 m/s - 43.2 m/s accelerating at 25.2 m/s², it would take the same amount of time

25.2 m/s² × x seconds = (144 - 43.2) m/s solve for x in seconds

x seconds = 100.8 m/s / 25.2 m/s²

x seconds = 4 (m/s /ms²) = 4 (m/s × s²/m) = 4 seconds the units match

x = 4 seconds
