Math problem ! and if you could explain how you got your answer that would be very !

-110 = 13 + 3(4h -6) . . . . . . given

-110 = 13 + 12h -18 . . . . . . . eliminate parentheses using the distributive property

-110 = 12h -5 . . . . . . . . . . . . collect terms

-105 = 12h . . . . . . . . . . . . . . add 5 to both sides of the equation

-105/12 = h = -8.75

There are many ways you can solve this. Another is to undo the operations done to h. The variable h is ...

When you undo these, you do it in reverse order:

-110 -13 = 3(4h -6) . . . . subtract 13

-123/3 = 4h -6 . . . . . . . divide by 3

-41 +6 = 4h . . . . . . . . . .add 6

-35/4 = h . . . . . . . . . . . divide by 4

h = -8.75

3/6   and 9/18

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
