it's d

are u sure this can be simplified?

thats the simplest form i can think of

if so, then j = 84 - 2k which is j = 84 - 2(4)

                                               j = 84 - 8

                                               j = 76                                              

do u mean what is j?

ok, lets say the length and width of the photo is l and w.

then, $2\left(l+w\right)=23$

and if the frame is 1 inch, $\left(l+1+1\right)\left(w+1+1\right)=58.5$

then we just solve the system of equations and get l = 7 and w = 4.5 so the area is 31.5

i got 100, is that right?

nice!

thanks!

thanks!!

correct!!
