The perimeter of rectangle abcd is 42 cm and the area is 80 cm2. which equation can be used to find the dimensions of the rectangle? (hint: set up a system of equations). xy + 2x + 2y = (42)(80) x^2 + 80x - 42 = 0 x^2 - 42x + 80 = 0 x^2 - 21x + 80 = 0

100 points, hi, i’m not sure how to get the equation from the graph and table.

Worth 100 points need the answers asap first row -x^2 2x^2 (x/2)^2 x^2 x is less than 2 x is greater than 2 x is less than or equal to 2 x is greater than or equal to 2 second row -5 -5/2 4 5 •2 is less than x& x is less than 4 •2 is less than or equal to x & x is less than or equal to 4 •2 is less than or equal to x& x is less than 4 •2 is less than x& x is less than or equal to 4

Which point has an coordinates of (2,0) ? a
