Answer: The lenght of the missing side is 4 cm
Step-by-step explanation:
The correct question is:
The perimeter of the rectangle is 20cm . One side is 6cm. What is the length of the missing side?
So, to answer it we have to apply the next formula:
Perimeter of a rectangle = 2 width + 2 length
Replacing with the values given: (assuming that the side given is the length of the rectangle)
20 = 2(6) + 2x
Solving for x:
20 =12 +2x
20-12 =2x
8 =2x
8/2 =x
4=x
The length of the missing side is 4 cm

Solve for x2= 9/49. Show your step-by-step.
Answer:
x = [tex]\frac{3}{7}[/tex], x = [tex]\frac{-3}{7}[/tex]
Step-by-step explanation:
The first step is to get rid of the square on the x, and to get rid of it, you square root both sides of the equation, like so:
[tex]x^{2} = \frac{9}{49}[/tex]
[tex]\sqrt{x^2} = \sqrt{\frac{9}{49} }[/tex]
A perfect square is when a number has two factors that are identical to one another. In this case, 9 and 49 are both perfect squares, meaning we can break them down:
The square root of 9 is 3. (3 · 3 = 9)
The square root of 49 is 7. (7 · 7 = 49)
x = [tex]\frac{3}{7}[/tex]
The answer is also x = [tex]\frac{-3}{7}[/tex] because a negative · a negative = a positive.

Step-by-step explanation:
The last two answer don't fit into the given equation, leaving the first two. For the first one, you do not use the square root of a number that is being squared. That's like saying you're going to fix a car, but the car is just fine and doesn't need fixed.

write an expression for the perimeter of the rectangle given 3x+4 and 2x-3
Answer:
2(3x+4) + 2(2x-3)
Step-by-step explanation:
this is because to be able to find the perimeter you use the formula 2(l) + 2(w)
The expression for the perimeter of the rectangle is 10x + 2.
What is the expression for the perimeter of the rectangle?Given the sides of the rectangle:
Length = 3x+4
Width = 2x-3
To determine the expression for the perimeter of the rectangle, we need to consider that the perimeter of a rectangle is given by the sum of all its sides.
The expression for the perimeter (P) is calculated as follows:
Perimeter = 2(Length + Width)
Plug these values into the perimeter formula:
P = 2(3x+4 + 2x-3)
Now, let's simplify the expression:
P = 2(5x + 1)
Finally, we can further simplify it:
P = 10x + 2
Therefore, the perimeter is 10x + 2.

Unit 6. 2) Please help. What is the probability that a student is absent given that today is Monday?
Enter your answer as a fraction in simplest form, formatted like this: 3/14
Answer:
Let's denote:
The probability that today is Monday: P(A)
The probability that a student is absent: P(B)
The probability that a student is absent given that day is Monday: P(B|A)
As given,
P(A intersect B) = 3/100
P(A) = 1/5
=> P(B|A) x P(A) = P(A intersect B)
=> P(B|A) = P(A intersect B)/P(A) = (3/100)/(1/5) = 15/100 = 3/20

Stefan bought 2 turkey sandwiches and 5 ham sandwiches for a total cost of $40.50. Nancy bought 4 turkey sandwiches and 1 ham sandwich for a total cost of $31.50. The equations below represent Stefan's and Nancy's purchases.
Answer:
Price of each turkey sandwich = $6.5
price of each ham sandwich = $5.5
2a + 5b = 40.50.........(i)
4a + b = 31.50..............(ii)
Step-by-step explanation:
Let
price of each turkey sandwich = a
price of each ham sandwich = b
Stefan purchase
2a + 5b = 40.50.........(i)
Nancy purchase
4a + b = 31.50..............(ii)
combine the equations
2a + 5b = 40.50.........(i)
4a + b = 31.50..............(ii)
b = 31.50 - 4a
insert the value of b in equation(i)
2a + 5b = 40.50.........(i)
2a + 5(31.50 - 4a) = 40.50
2a + 157.5 - 20a = 40.50
-18a = 40.50 - 157.5
-18a = -117
divide both sides by -18
a = -117/-18
a = 6.5
insert the value of a in equation(ii)
4a + b = 31.50..............(ii)
4(6.5) + b = 31.50
26 + b = 31.50
b = 31.50 - 26
b = 5.5
Price of turkey sandwich = $6.5
price of ham sandwich = $5.5

Suppose you have a rectangle with a perimeter of 2 cm. What can you conclude about the side lengths? Can all 4 sides of the rectangle measure a whole number of centimeters?
Answer:
Step-by-step explanation:
The formula for a perimeter of a rectangle = 2(L+B)
= 2L+2B
Where L and B are length and breadth respectively.
The question says ;
2cm = 2(L+B)
2cm = 2L+2B
Divide both sides by 2
1 = L+B
If the sum of the length and breadth is equivalent to 1cm, then the length itself is less than 1 cm. That is L < 1 cm
When all sides of the rectangle is summed, it will definitely be a whole number since the perimeter is 2 cm
