Answer:
Step-by-step explanation:
Assuming the question is x^2 + 6x = 27x, subtract 6x from both sides. x^2 = 21x. Then, divide both sides by x and you get x= 0, 21
The apothem is the distance from the center to the midpoint of one of the sides of a regular polygon. You can make a right triangle with the apothem, the line from the midpoint to the corner and the line from the center to the corner. An equilateral triangle has 60 degree angles (180/3). The right triangle has half of one of those angles so 30 degrees. Now we have a 30-60-90 triangle where the short leg is 5cm. The long leg, which is also half of one side of the triangle is thus
. A whole side of the triangle is
. Multiply that by 3 to get the perimeter of <span>

Step-by-step explanation:
Mean vs Median
The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30.
The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.
Answer:
He omitted the value "6" from the input value and added it to the output values. Also, he omitted the value "12" as an output value.
Step-by-step explanation:
Bobby didn't map the relation well. He omitted "6" which is supposed to be an input value and rather included it among the output values (y-values).
"12" was omitted also under output values.
All of these make the the relation not to be a function anymore.
If Bobby had mapped the relation well, the ordered pair would have obviously been a function as every x-value will have exactly one y-value assigned the it.
