Here i hope this helps you with the problem
51 = 3k ( take 3 to the other side )
51/3 = k ( multiplication becomes division )
17 = k
k = 17
x(b+c)+3(b+c) = (x+3)(b+c)
Answer: 4). A = (b1 + b2)h/2
5).
A = (b x h)/2
6). A = b x h
7). A = b x h = 65 x 50 = 3250 ft^2
8). A = (b x h)/2 = (12 x 18)/2 = 108 inches^2
9). A = (b1 + b2)h/2 = (15 + 7)4/2 = 44m^2
The y-intercept of the graph equation is (0,-4)
