Aline segment can be drawn from each vertex of a polygon to every other vertex, forming the sides and diagnosis of the polygon. a square, for example, has 4 sides and 2 diagonals. using combinations, write an expression that would give you total number of sides and diagonals for a polygon with n sides

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
