Answer:
The minimum number of Vinyl peel and stick floor tiles needed is 216 Tiles
Step-by-step explanation:
Here we have area size of Vinyl peel and stick floor tiles = 1 ft²
Size of floor of rectangular room = 12 ft × 14 ft = 168 ft²
Size of floor on rectangular hallway = 12 ft × 4 ft = 48 ft²
Total area of floor in rectangular room and rectangular hallway
= 168 ft² + 48 ft² = 216 ft²
Therefore number of Vinyl peel and stick floor tiles needed =
(Total area of floor in rectangular room and rectangular hallway)÷( Area size of Vinyl peel and stick floor tiles) = 216 ft²/(1 ft²) = 216
Therefore the minimum number of Vinyl peel and stick floor tiles needed = 216 Tiles.

Answer:
b
Step-by-step explanation:
Given
x³ + 5x² - 9x - 45 ( factor the first/second and third/fourth terms )
= x²(x + 5) - 9(x + 5) ← factor out (x + 5) from each term
= (x + 5)(x² - 9) ← factor as a difference of squares
= (x + 5)(x - 3)(x + 3)
U can use the second last one
X + 90 = 2x + 40
