B and C
because the second number is a square of the first number
Answer:

Step-by-step explanation:

20x+3
This shouldddd be the answer sorry if I’m wrong, but if you group all the x variables together they add up to twenty, then you just add “+3” being that it has no x and therefore must be put in some form of separate group!
So scale is 1 inch= 8 ft
so, 26 inches = 8×26 = 208 ft
and , 35 inches = 8×35 = 280 ft
so the actual area= 208×280 = 58240 sq ft !
