Answer:

Step-by-step explanation:

4 6 10 18 34 66 130 n^2+2

1 4 9 16 25 36 49 n^2

2 4 8 16 32 64 128 2^n

2 6 12 20 30 42 56 n^2+n

this is Fibonacci, 1 1 2 3 5 8 13 21, and its hard to come up with a rule because you need to know the number one before and two before and add them together.

Which is a solution to (x – 3)(x + 9) = –27? x = –9 x = –3 x = 0 x = 6

likoan [24]

Answer:

x = 0

Step-by-step explanation:

Since the product is not equal zero, we need to multiply both parenthesis first:

$(x-3)(x+9) =-27$

$x*x+x*9+(-3)*x+(-3)*9=27$

$x^2+9x-3x-27=27$

$x^2+6x-27=27$

Add 27 from both sides:

$x^2+6x-27+27=-27+27$

$x^2-6x=0$

Factor $x$ out:

$x(x+6)=0$

Apply the zero product:

$x=0,x+6=0$

$x=0,x=-6$

The solutions of the equation are $x=0$ and $x=-6$ .

We can conclude that the correct answer is x = 0.

Ariel has made a circular flower garden in her yard and she would like to put a plastic border around it. The garden has a radiu

bezimeni [28]

Answer:

She will need approximate $50.24\ ft$ of plastic border

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

In this problem we have

$r=8\ ft$

substitute

$C=2\pi (8)=16 \pi\ ft$ ----> exact value of the length of plastic border

assume

$\pi=3.14$

$16 (3.14)=50.24\ ft$ ---> approximate value of the length of plastic border

==========================================================

Solving :

Therefore, the equation is :
