Select the correct answer. Two buildings on opposites sides of a highway are 3r3 – 12 + 78 + 100 feet apart. One building is 2x2 + 70 feet from the highway. The
other building is 13 + 2.12 – 18 feet from the highway. What is the standard form of the polynomial representing the width of the highway
between the two buildings?
OA. 13 + 412 + 71 - 18
OB. 203 - 5.02 + 118
OC 2:3 + x2 + 71 + 118
OD 3.13 - 3r2 + 100
