Answer:
Let the adjacent angles of the rhombus be 2x and 3x. We know that the sum of the measures of the adjacent angles is equal to 180°. AD = DC = 3 × 36° = 108°. Hence , the angles of the rhombus are 72° , 108° , 72° and 108°.
Step-by-step explanation:
Dont quote me on this but i think it is 10 because 86 × 2 is 172 and 297 ÷ 172 is 10 I think
15 is 30% of
50 Change the percentage to a decimal by dividing it over 100:

Divide 15 over 0.3:
-2(2x-1)(x+3) = ((-2)2x - (-2)(-1))(x+3) = (-4x-2)(x+3)
In the general case, it is (x, y+3), where y = f(x).
