Multiplication is really just repeated addition.
Answers:
- 10 x 3 or 10(3)
- 4 x 7 or 4(7)
- 8 + 8
- 3 + 3 + 3 + 3 +3 + 3 + 3 + 3 + 3
- m + m + m + m + m + m
- 5d
Answer: 
Step-by-step explanation:
To find the equation from a graphed function, you can substitute points into each equation to find the original:
A point on the graph is (2, 4). Substituting this into each equation, we get:
, which claims that 4 is equal to 30, which is incorrect.
, which claims that 4 is equal to 3/2, which is incorrect.
, which claims that 4 is equal to 4, which is correct.
We can test the third function further by taking another point on the graph, (3, 5), and substituting it into the function:
, which claims that 5 is equal to 5, which is correct.
Answer:
the answer is c
congruence can happen in any shape as long as all the angles and sides match up

Step-by-step explanation:
Speed is distance traveled per block of time. As an equation, this is
Speed = distance/time
In your problem, the given distance is 300km, and the time is 2.5 hours.
Plugging into the equation,
Speed = 300km / 2.5 h
Speed = 120 km/h
Velocity is speed <em>and</em> direction.
The velocity would be 120 km/h north.
