Which set of measurements could be the side lengths of a triangle?

a.)3m, 6m, 3m
b.)4m, 7m, 12m
c.)9m, 5m, 3m
d.)4m, 11m, 9m

D.) 4m, 11m, 9m

Step-by-step explanation:

According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be larger than the third side in order to form a triangle.  Using the two shortest sides, you can find the sum and check to make sure it is larger than the third:

3m + 3m  = 6m NOT greater than 6m

4m + 7m = 11m NOT greater than 12m

5m + 3m = 8m NOT greater than 9m

4m + 9m = 12m YES greater than 11m

it is c, trust i got your back lol

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
