A circular garden is surrounded by a rectangular grassy area. The garden takes up nearly half the grassy area. The base of the g
d1i1m1o1n [39]

Answer:

The area of the circular garden is approximately 7.1 square yards

Step-by-step explanation:

The given parameters are;

The area surrounding the circular garden = A rectangular grassy area

The area of the circular garden ≈ (1/2) × The base of the grassy rectangular area

The dimensions of the base of the rectangular grassy area = 6 yards by 3 yards

The diameter of the circle, D = 3 yards

The area of the rectangular grassy area = 6 yards × 3 yards = 18 yards²

∴ The approximate area of the circular garden = (1/2) × 18 yards² = 9 yards²

The area of the circular garden, A = π·D²/4

∴ A = 3.14 × (3 yards)²/4 = 7.065

The area of the circular garden, A ≈ 7.1 yd².

If p(x) = x2 – 1 and 9(x) = 5(x-1), which expression is equivalent to (p - 9)(x)?
Westkost [7]

For this case we have the following functions:

p (x) = x ^ 2-1\\9 (x) = 5 (x-1)

We must find (p-9) (x). By definition of composition of functions we have:

(p-9) (x) = p (x) -9 (x)

So:

(p-9) (x) = x ^ 2-1- [5 (x-1)] = (x ^ 2-1) -5 (x-1)

Thus, the correct option is option C.

Answer:

(x ^ 2-1) -5 (x-1)

Option C

14x - 9 + 8x + 3 = 9x - 8 - 3x - 14<br> One Solution<br> Infinitely Many Solutions<br> No Solution
Oliga [24]

Answer:

\large\boxed{\text{One solution.}}

14x - 9 + 8x + 3 = 9x - 8 - 3x - 14

Combine like terms:

14x + 8x - 9 + 3 = 9x - 3x - 8 - 14

22x - 6 = 6x - 22

Subtract 6x from both sides:

22x - 6x - 6 = 6x - 6x - 22

16x - 6 = -22

Add 6 to both sides:

16x - 6 + 6 = -22 + 6

16x = -16

Divide both sides by 16:

16x/16 = -16/16

x = -1. There is only one solution to this equation.
