Pisces is replacing paving stones for her inground pool. Her pool is 10m by 5m and is surrounded by a 1 1/2 border of paving stone. If each paving stone was 25 cm by 40 cm, in theory, how many paving stones will she need?
Answers
Answer:
The number of paving stones she needs is 540 paving stone
Step-by-step explanation:
The given dimensions of Pisces' inground pool = 10 m by 5 m
The thickness of the border surrounding the pool = 1 1/2
The dimensions of each paving stone = 25 cm by 40 cm = 0.25 m by 0.4 m
The length dimension of the pool and border = 10 + 2 × 1 1/2 = 13 m
The width dimension of the pool = 5 + 2 × 1 1/2 = 8 m
The total area of the paving stone, [tex]T_A[/tex] = Area of pool + border - Area of pool
∴ [tex]T_A[/tex] = 13 m × 8 m - 10 m × 5 m = 54 m²
The total area of the paving stone = 54 m²
The area of each paving stone, [tex]A_{EP}[/tex] = 0.25 m × 0.4 m = 0.1 m²/paving stone
The number of paving stones she needs, n = (The total area of the paving stone)/(The area of each paving stone)
∴ n = 54 m²/(0.1 m²/paving stone) = 540 paving stone.

which is the correct input-output table for the function g(x)=-1/2(4x+6)
Answers
Answer: The third choice.
Step-by-step explanation: To find the first output, start with your first input. In this case, it's -2, so your equation would be g(-2)= -1/2(4(-2)+6). Start by solving inside the parenthesis. 4x-2=-8 and -8+6=-2. -1/2x-2= 1, so your first output should be 1. The only choice that has this is the third one, so that is your answer. Hope I could help :)

Solving by factorising
Given
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
