Which function is represented in the graph

Which expression is factored form? x^2+14x+48 a) (x-8)(x-6) b) (x+6)(x-8) c) (x+8)(x-6) d) (x+6)(x+8)

Arectangle has a width of 5 cm and a length of 10 cm. if the width is increased by 3, how does the perimeter change?

Find an bif a = {3, 6, 9, 12) and b = {2, 4, 6, 8, 10).
