How many triangles can be constructed with sides measuring 6 cm, 2 cm, and 7 cm?
a. one
b. more than one
c. none

 Option A- One                      

Step-by-step explanation:

Given that : The sides of the triangle  measuring 6cm, 2cm and 7cm.

We are using : Triangle inequality

The sum of the length of the two sides should be greater than the length of the third side.

So, when we apply this theorem in 6cm,2cm and 7cm

6+2=8>7 , 7+2=9>6 , 7+6=13>2

It satisfy all three possible sets.

Therefore, the given values follows the triangle inequality.

Hence one triangle can be formed.

Therefore, option A is correct.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

the answer is b
