=-12

B -12

Step-by-step explanation:

(-4)3 is just -4 times 3 which is -12.

4x3=12 -4x3=-12

because only one number is negative the answer becomes negative.

if neither number was negative the answer would be positive.

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
