Question

Find the vaule of (7y+8)°
(8y+7)°

Answer 1

The expression (7y+8)° is a degree measure and does not have a numerical value. Similarly, the expression (8y+7)° is also a degree measure and does not have a numerical value.

If these expressions represent angles in a geometric figure, such as a triangle or a quadrilateral, then the values of y could be determined by applying the relevant geometric rules and solving the resulting equations.

Answer 2

I wasn’t able to tell what you wanted done with this equation but here’s what I came to

(Combining the equation)
15y+15

(This is if your multiplying the equation)
56y^2+113y+56

Hope this helps
