Find the least common multiple. 3x^3, 12y^2, and 15xy^3

3

Step-by-step explanation:

x is missing from 12y^2

y and 2 and 5 are missing from 3x^3

3 is present in all monomials.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
