The answer for this problem i −10x2+66xy−36y2−5x+3y

Let's solve it by step by step.

(−5x+3y)(2x−12y+1)

=(−5x+3y)(2x+−12y+1)

=(−5x)(2x)+(−5x)(−12y)+(−5x)(1)+(3y)(2x)+(3y)(−12y)+(3y)(1)

=−10x2+60xy−5x+6xy−36y2+3y

So, -10x2+66xy-36y2-5x+3y

rosijanka [135]

Answer:

The correct answer is 3 × 5 + 3 × 7 + 6 × 7 = 78 square feet.

Step-by-step explanation:

Measures of Chad's window is 36 inches by 60 inches = 3 feet by 5 feet.

Area of the window is 15 square feet.

Measures of Chad's door is 36 inches by 84 inches = 3 feet by 7 feet.

Area of the door is 21 square feet.

Measures of Chad's closet is 72 inches by 84 inches = 6 feet by 7 feet.

Area of the closet is 42 square feet.

Equation to show the total area of window, door and closet is 15 + 21 + 42 = 78 square feet.
