Arectangle has an area of (x^2-17x+72) square units. since the areas of the rectangle is determined using the formula, a=lw, what could be the length and width of the rectangle?

a: length= (x-8) units and width = (x-9) units
b: length = (x+9) units and width = (x+8) units
c: length = (x-6) units and width = ( x-12) units
d: length = (x =12) units and width = (x +6) units

Rob spent 25%, percent more time on his research project than he had planned. he spent an extra h hours on the project. which of the following expressions could represent the number of hours rob actually spent on the project? two answers

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.
