Question

Olivia helps paint a square mural in her classroom. Then she helps paint a

mural in the hallway whose length is 5 feet longer and whose width is 2 feet
shorter. Let represent the side length of the mural in Olivia's classroom
Write an expression that represents the two binomials you would multiply to
find the area of the hallway mural. Use that expression to find the area of the
hallway mural if each side of the classroom mural is 7 feet long.
O A. (x - 5)(x+ 2); 18 square feet
O B. (x+3)(x + 2): 108 square feet
O c. (x+5)(x - 2); 60 square feet
O D. (x - 5)(x - 2); 10 square feet

Answer 1

C

Explanation:

Assuming the side length of the square is x, we know that the length of the rectangle is 5 more than that, or x+5. Then, the width of the rectangle is 2 less than x, or x-2. The area of a rectangle is width multiplied by length, so our answer is (x+5)(x-2), or C
