Is there a solution for the lines: x + y = 3 and 2x + 2y = 6.

there is infinite numb of solutions since those lines are the same (if you divide both sides of 2nd equation by 2 you will get the same as the first equation)

Step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

the answer

b. they are parallel and will never intersect.
