Answer:
x = ± 2
Step-by-step explanation:
Given
2x² + 11 = 131 ( subtract 11 from both sides )
2x² = 120 ( divide both sides by 2 )
x² = 60 ( take the square root of both sides )
x = ± = ± = ± 2
The sketch of the garden and the pond is shown below
Area of garden = length × width
Area of garden = [3x + 5] × 3x
Area of garden = 3x[3x+5]
Area of garden = 9x² + 15x
Area of pond = [x-2] × x
Area of pond = x[x-2]
Area of pond = x² - 2x
Area to be re-sod = Area of garden - Area of pond
Area to be re-sod = 9x² + 15x - [x² - 2x]
Area to be re-sod = 9x² - x² + 15x + 2x
Area to be re-sod = 8x² + 17x
The amount of sod needed to be bought would depend on how much in each packaging they are being sold.
Answer:
-1/6
Step-by-step explanation:
first you need to reduce the numbers with the greatest common divisor (2)
so, divide 2 and 4 by 2. you'll get 1 and 2.
-1/6 x 1/2
then you just multiply the fractions.
Answer:
Step-by-step explanation:
11 and 12
A, B, and C
121, 120, and 111 all are smaller then or equal to 121, which has the square root of 11, so they are less than or equal to 11 in that inequality
