Please help me with those questions please please help

Step-by-step explanation:

1)

Prime factorization of 36 is: 2 x 2 x 3 x 3.

Prime factorization of 196 is: 2 x 2 x 7 x 7.

Prime factorization of 361 is: 19 x 19.

2)

Greatest Common Factor of 126 and 144 is: 18.

Least Common Multiple of 28, 42, and 63 is: 252.

3)

2/3+3/4=17/12.

2/3-3/4= -1/12.

3 2/3 x 1 3/4 = 6 5/12.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
