What you should do is draw a figure of the picture with the frame around it. Call the height of the inside rectangle (picture) h. Then the width of the picture would be labeled as 2h + 3. The frame's dimensions are 2.5 inches on each end, so the frame's dimensions are found by addin 5 to the picture's dimensions. That is (h+5) and (2h + 3 + 5) or (2h + 8)
The combined area is (h+5)(2h + 8). Multiply out if you want.

The painting:
If x = painting height in inches, then
2x + 3 = painting width in inches
And area of the painting with the frame would be:
(x + 5)(2x + 8) because the 2.5" frame adds 5 inches to the height and width.
OR 2(x+5)(x + 4) square inches

jointly Alan, Betty, and Chris have $31. A+B+C = 31: Eqn a million discover the quantity each and each has if Betty has $3 below Alan, B = A-3 : Eqn 2 and Chris has $a million extra desirable than Alan and Betty mixed. C = A + B + a million : Eqn3 positioned eqn 2 into eqn a million and into eqn 3 A + A -3 + C = 31 2 A + C = 34 : eqn 4 C = A + A-3+ a million 2 A - C = 2 : Eqn 5 upload eqn 4 & eqn 5 4 A = 36 A = 9 B = A -3 = 9 -3 = 6 A+B+C = 31 9+6 +C = 31 15+ C = 31 C = sixteen

A=(8+2h)(5+h)
A=40+8h+10h+2h^2
A=2h^2+18h+40

Maybe I have it right but make sure someone comes up with the same answer......
Area = H+2.5 x (2H+5.5)
H = Height.

i believe that it is 6.25 inches because 2.5x2.5=6.25...since the frame goes around the whole painting.
