Tim has decided to add a wraparound porch to his beach cottage so that he can spend more time outside. His cottage is 45 feet long and 25 feet wide. The porch will go around three sides of the cottage and be the same width on all sides.The total area of the cottage and porch together in square feet can be modeled by the expression (45+2x)(25+x), where x is the width of the porch in feet. This expression can be also written in the form 2x2+95x+1,125.What does the quantity 2x2+95x represent in the expression?Choices:(A)the perimeter around the outside of the porch in feet(B)the area of the cottage in square feet(C)the area of the porch in square feet(D)the length of the cottage and porch together in feet
Q. Tim has decided to add a wraparound porch to his beach cottage so that he can spend more time outside. His cottage is 45 feet long and 25 feet wide. The porch will go around three sides of the cottage and be the same width on all sides.The total area of the cottage and porch together in square feet can be modeled by the expression (45+2x)(25+x), where x is the width of the porch in feet. This expression can be also written in the form 2x2+95x+1,125.What does the quantity 2x2+95x represent in the expression?Choices:(A)the perimeter around the outside of the porch in feet(B)the area of the cottage in square feet(C)the area of the porch in square feet(D)the length of the cottage and porch together in feet
Expand Expression: The expression for the total area is (45+2x)(25+x). Let's expand this to see what each term represents.
Calculate Cottage Area: First, multiply 45 by 25 to get the area of the cottage without the porch.45×25=1125 square feet.
Calculate Porch Areas: Next, multiply 45 by x and 25 by 2x to get the area of the porch on the long side and the short side, respectively.45x+50x=95x square feet.
Determine Total Area: Finally, multiply 2x by x to get the area of the porch on the corner, which wraps around twice.2x×x=2x2 square feet.
Identify Porch Area: Now, we have the expanded form: 2x2+95x+1125. The 1125 represents the area of the cottage, and the terms 2x2+95x represent the area of the porch.
Identify Porch Area: Now, we have the expanded form: 2x2+95x+1125. The 1125 represents the area of the cottage, and the terms 2x2+95x represent the area of the porch.So, the quantity 2x2+95x represents the area of the porch in square feet.
