For the perimeter use the formula 2x3.14xr
step 1: divide the 20 by 2
step2:multiply 3.14 by the qoutient of the division
step3:divide again by 2
For the area the formula is 3.14 x r x r
the r is the qoutient on step one
step 1: multiply both Rs
step2: multiply the 3.14 by the product of step one.
and you are done i hope it helps you

Heidi solved the equation
3(x + 4) + 2 = 2 + 5(x – 4). Her steps are below:
3x + 12 + 2 = 2 + 5x – 20
3x + 14 = 5x – 18
14 = 2x – 18
32 = 2x
16 = x
Use the drops-downs to justify how Heidi arrived at each step.
Answers
Answer:
her first step was) Combining like terms= 12+2
her second step was) Combining like terms/ subtracting 5x from 3x= 5x-3x
her third step was) Adding to both sides 18= 14+18
her last step was) isolating the variable/ dividing 2 from both sides= 32/x.

Answers
Hi there!
[tex]\large\boxed{x = 2.5}[/tex]
We can solve for x by using an elimination of variables.
2x + 5y = 20
-2x + 10y = 25
Add the two equations to eliminate x:
0x + 15y = 45
15y = 45
y = 3
Substitute this value of y into an equation to solve for x:
2x + 5(3) = 20
2x + 15 = 20
2x = 5
x = 2.5

Look at the sequence of numbers.
6 12 18 24
a Write down the next number in the sequence.
b Write down the term-to-term rule.
C Write down the position-to-term rule.
Answers
Answer:
Here we have the sequence:
6, 12, 18, 24
We can assume that this is an arithmetic sequence, this is, the difference between any two consecutive terms is always the same, D.
To check this, let's find the difference between the consecutive terms:
12 - 6 = 6
18 - 12 = 6
24 - 18 = 6
So we can conclude that this is an arithmetic sequence, and the difference between any two consecutive terms is always 6.
a) Then the next number in the sequence will be equal to the previous number plus 6, this is:
24 + 6 = 30
The next number in the sequence is 30
b) The term-to-term rule is the rule that defines the n-th term based on the previous terms.
Here we already know that each term in this sequence is the previous one plus six, so we can write this as:
Aₙ = Aₙ₋₁ + 6
c) The position-to-term rule is the general one.
Here we need to know that, the first term, A₁ = 6
Then, the n-th term will be A₁ plus (n - 1) times 6.
Then the rule is:
Aₙ = A₁ + (n - 1)*6
Replacing A₁ by its value, the rule becomes:
Aₙ = 6 + (n - 1)*6

If one zero of the quadratic polynomial x2 - 7x + 5k is -2, then find the value of k
Answers
Answer:
k = - 3.6
Step-by-step explanation:
Given x = - 2 is a zero then f(- 2) = 0
Substitute x = - 2 into the polynomial and equate to zero
(- 2)² - 7(- 2) + 5k = 0
4 + 14 + 5k = 0
18 + 5k = 0 ( subtract 18 from both sides )
5k = - 18 ( divide both sides by 5 )
k = - 3.6

Find the equation of the circle with center (4, 4)
and radius of 7.
A (x-4)+(y+4)*= 49
B (x– 4) +(y - 4) = 49
C (x+4)² – (y + 4) = 7
D (x+4)*+(y+4)2=7
Answers
a and b are the centre and you put in the inverse so as x=-4, a=-4. same for b as the y-coordinate is positive, it becomes negative
the last part is the radius of the circles squared so just 7^2 = 49 !

John received a shipment of 3 crates, this was only 20% of his total order. How many crates did John order in all?
Answers
Answer:
Total number of crates John order = 15 crates
Step-by-step explanation:
Given:
Total number of crates John received = 3 crates
Amount of order John received = 20%
Find:
Total number of crates John order
Computation:
Total number of crates John order = Total number of crates John received / Amount of order John received
Total number of crates John order = 3 / 20%
Total number of crates John order = 3 / 0.2
Total number of crates John order = 15 crates

The line that goes through the points (0,-4) and (1,2) is......
Answers
Answer: The equation for the line is “y = 6x - 4”
Step-by-step explanation: To find this answer we will put it in slope-intercept form which is y = mx +b. To first find m which is the slope you subtract the the second y by the first y over the second x by the first x. It looks like this y2 - y1/ x2 - x1. After we find the slope which is 6, to find the y-intercept which is b we just plug a point we used to find the slope into the equation we have. It looks like this y = 6x + b —> 2 = 6(1) + b... I used (1,2). Then you solve for b by multiplying 1 by 6 and then subtracting 6 to both sides to get b by itself. So it goes from 2 = 6(1) + b into -4 = b. Then you just put -4 into b and you get the answer y = 6x - 4.
