Find the perimeter of a triangle with sides measuring 3 centimeters, 4 centimeters and 5 centimeters.
a.
20 cm
c.
19 cm
b.
12 cm
d.
14 cm

12

Step-by-step explanation:

P=a+b+c       P=3+4+5    P=12

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
