The perimeter is the length of all 6 sides added together. So say each side equals 2. Then your equation would be 2+2+2+2+2+2. or. 6x2. 6x would be your answer

Each side is x units long. There are 6 sides. So we add up all the sides to get the perimeter.
x+x+x + x+x+x
there are six copies of x being added

Simplifying that expression above leads to 6*x or simply 6x. Multiplication is a shortcut for repeated addition. Instead of saying 2+2+2+2, we can write 4*2

Answer: Choice C) 6x

What is the value of K

Elan Coil [88]

Answer:

k = 10

Step-by-step explanation:

We first have to get the 3rd angle: 180 - 115 = 65

Sum of angles in a triangle = 180

65 + (4k + 5) + (6k + 10) = 180

Collect like terms

65 + 10k + 15 = 180

80 + 10k = 180

Subtract 80 from both sides

10k = 100

Divide both sides by 10

k = 10

Jims fish bowl contains x tetras, 3 goldfish, and 5 platies. He removes one fish from the fish bowl at random. If the probabilit

My name is Ann [436]

Answer: x = 1

Step-by-step explanation:

we have

x tetras

3 goldfish

5 platies.

the total number of fishh in the bowl is x + 3 + 5

The probability of removing a gold fish is equal to the number of gold fish divided by the total number of fish, this is:

p = 3/(x + 3 + 5) = 1/3

3 = (1/3)(x + 3 + 5) = x/3 + 1 + 5/3

9 = x + 3 + 5

x = 9 - 8 = 1

then wemust have that x = 1

because 1 + 3 + 5 = 9

and 3/9 = 1/3

What is the general equation of a sine function with an amplitude of 6, a period of StartFraction pi Over 4 EndFraction, and a h

Katen [24]

Answer:

C: $y = 6 \sin (8(x-\frac{\pi}{2} ))$

Step-by-step explanation:

Amplitude is changed by multiplying the entire trig function by a number, by default the amplitude is 1, so multiplying by 6 is necessary; eliminate A and B

Horizontal shift is going through the x axis, so it must be subtracted from the x value. This is only seen in choice C of the remaining answers.

Calculating the period isn't necessary because we already found the right answer but in case you need it in the future; the period is by default 2pi, to get to pi/4, it had to be 8 times smaller, so multiplying x and translations on x by 8 will get you the correct period.
