Answer: x^2-9x+1
Step-by-step explanation:
x^2-7x-7 d(x-1)
(you would just replace x to (x-1)
(x-1)^2-7(x-1)-7
(solve by square rooting (x-1)(x-1) then foil)
x^2-9x+1
Answer:
Explanation:
In this problem, the amount of wood refers to the length of the frame, modeling it as a long piece of wood.
Thus, the amount of wood is equal to the perimeter of a rectangle with dimensions <em>width = 8 inches</em>, and l<em>ength = 3×8 inches = </em>24 inches.
The perimeter of a rectangles is 2 × width + 2 × length:
- 2 × 8 inches + 2 × 24 inches = 16 inches + 48 inches = 64 inches.
