Answer:

15x^2+380x+2400

The diagram is shown below for reference.

Step-by-step explanation:

We are given the length and width of old pumpkin patch as 60 meters and 40 meters respectively.

It further says length is increased by 5x meters and width increased by 5x meters.

So the length of the new pumpkin patch would be 60+5x meters.

And the width would be 40+3x meters.

We know area of a rectangular shape =length \times width

So, plugging the above values, we get the area of the new pumpkin patch as:

=(60+5x)\times (40+3x)\\=2400+180x+200x+15x^2\\=2400+380x+15x^2\\=15x^2+380x+2400 on rearranging.

Thus the function of the area of the new pumpkin patch would be:

f(x) = 15x^2+380x+2400

sladkih [1.3K]

The probability that the arrow will land on any of them <em>once</em> is 1/4.

The probability that the arrow will land on any of them <em>twice</em> is 1/4 * 1/4. This is because the probability of Event A <em>and</em> Event B is P(B) * P(A).

Based on this:

P(a\cap b\cap c\cap d) = \frac{1}{4}\times \frac{1}{4}\times\frac{1}{4}\times\frac{1}{4}\\\\=\frac{1}{4\times4\times4\times 4}\\=\frac{1}{256}

1/256

Hope this helps, let me know if I missed anything!

Let h(x) = (g o f)(x) = sqrt{x+3}
Debora [2.8K]
I am assuming you meant to write the following options

A. f(x)=x+3; g(x)=√x
B. f(x)=x; g(x)=x+3
C. f(x)=√x; g(x)=x+3
D. f(x)=3x; g(x)=√x

You need to find a fucntion f(x) that once evaluated in g(x) gives us as a result h(x)

h(x) =  g(f(x))

Looking at the options, the answer is A.

g(f(x)) = sqrt(f(x)) = sqrt (x + 3) = h(x)

Find the discriminant of x²+6x+9=0 ​
Rainbow [258]

Answer:

x²+6x+9=0

x²+3x+3x+9=0

x(x+3)+3(x+3)=0

(x+3)(x+3)=0

either

x+3=0

x=-3

or

x+3=0

x=-3

Step-by-step explanation:

next method

x²+6x+9=0

x²+2×x×3+3²=0

it is in formula of (x+y)²

(x+3)²=0

x+3=√0

x+3=0

x=-3
