This is a math expression that tells you the order of operations. It does not matter the order that you multiply these numbers in for this equation.

13 * (-3) * (-7) * (-3) = ?

13 * (-3) = -39          -7 * (-3) = 21 (Negatives cancel out)

-39 * 21 = -819

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

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis
