The preimeter of a rectangle is 44m if the widthe were doubled and the length were increased by 8, the preimeter would be 76m what is the length of the rectangle

Thus, the length of the rectangle is 14m

In order to find the number of hours of work at which they will have the same amount, you will need to find both their equations and then equalize them to find when they are the same. Let x be the number of hours Fernando: intial 10$ = constant and we multiply x by the 4$ he takes per hour. The whole has to be multiplied by 0.30 (30%) since that is the only part he keeps Therefore, yf=0.3(4x+10) Brenna: same logic yb=0.25(6x) To find when they are equal: yf=yb 0.3(4x+10) = 0.25(6x)
