The answer is 2x^2+2x-14. Using the distributive property, you can find that the area of the pool is x^2+3x+2. Next, you have to find the area of the deck. This will be 3x^2+5x-12. Finally, you subtract the area of the deck by the area of the pool. (3x^2+5x-12)-(x^2+3x+2) comes out to be 2x^2+2x-14. Hope this helps!!

Gina is cutting construction paper into rectangles for a project. She needs to cut one rectangle that is 12 inches by 14 1/4 inc

Fittoniya [83]

Answer:

278.63 square inches

Step-by-step explanation:

Gina needs to cut two types of rectangles.

Dimensions of one rectangle is given as,

Width = 12 inches

Length = $14\frac{1}{4}$ = $\frac{57}{4}$ inches

So, the area of this rectangular paper will be

Area = width × length = $12\times \frac{57}{4}$ = 171 inches²

Dimensions of the other rectangular paper has been given as

Width = $10\frac{1}{4}$ = $\frac{41}{4}$ inches

Length = $10\frac{1}{2}$ = $\frac{21}{2}$ inches

So, the area of this rectangle will be

Area = width × length = $\frac{41}{4} \times \frac{21}{2}$ = 107.63 inches²

Thus the total area she need to cut = 171 + 107.63 = 278.63 square inches.
