Divide the pentagon into a triangle and rectangle.
Rectangle: 12in*6in=72in^2
Triangle: (12in*5in)/2=30in^2
72in^2+30in^2=102in^2
Answer:
The answer is 8 because 28=50- 4n we have to group like terms so 28- 50= -4n therefore 28-50 will be -32 = -4n therefore we have to divide both side by the coefficient of n that is -4 and minus 4 goes to itself 1 and to - 32 8 because the minus sign will cancel the minus
