Answer:
The ares in factorised form is C. (x-8)(x-6)
When expanded it is G. x^2-14x+48
Step-by-step explanation:
The rectangular photo is mounted on a piece of board whose sides have length x. The border that surrounds the photo is 3 inches on each side and 4 inches on both the top and the bottom.
Area of rectangle is length × breadth
Length of rectangle (x - 4 - 4) = (x - 8) inches
Breadth of rectangle (x -3 - 3) = (x -6) inches
Thus, area of photograph = (x - 8)(x -6) inches².
Expanding it by opening the bracket
x(x-6)-8(x-6)= x^2-6x-8x+48=x^2-14x+48
Thus; C and G is correct
