Answer:
A pentagon has five sides
The first one is A,B,and D because for A a function on a graph rises from left to right.B because the input or x is not repeating so just remember that too many x's ain't right but more than one y or output is okay.D because each x is not repeating which is a no no in functions.The second question is the first one is a function and the rest no because the first one none of the x or repeating the other ones their x in their data set is repeating.
(8x+32)/4= 2x+8
2x+8=y+7 With y being the length of a side of square b
y=2x+1
Perimeter of square b: 4(2x+1)=8x+4
Or you could just do this:
32-4(7)=4 so Perimeter of b is 8x+4
The answer is c (x+21) and (x-2) you have to find two numbers that multiply yo give you -42 and add to give you 19
