Value of x is 4 and length of QR is 15cm.
Define parallelograms.A parallelogram is a geometric object with sides that are parallel to one another in two dimensions. It is a form of polygon with four sides (sometimes known as a quadrilateral) in which each parallel pair of sides have the same length. A parallelogram has adjacent angles that add up to 180 degrees. A unique variety of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal. The illustration displays a parallelogram ABCD with the coordinates AB II CD and AD II BC. Moreover, AB = CD and AD = BC. Non-Example: A parallelogram is not represented by a trapezium.
Given Data
In rectangle, two parallel line are equal.
PS = -1+ 4x
QR = 3x +3
So,
Value of x will be:
-1 + 4x = 3x +3
4x - 3x = 3 +1
x = 4
For length of QR,
3x +3
3(4) +3
12 +3
15
Value of x is 4 and length of QR is 15cm.

If (ax + 3)(bx + 4) = 6x 2+ cx + 12 for all values of x, and a + b = 5, what are the two possible values for c ?
Answers
Answers: c = 17 and c = 18
==================================================
Explanation:
Let's expand out the left hand side and rearrange terms like shown in the steps below.
(ax + 3)(bx + 4) = 6x^2 + cx + 12
ax(bx + 4)+3(bx + 4) = 6x^2 + cx + 12
abx^2 + 4ax+3bx + 12 = 6x^2 + cx + 12
abx^2 + (4a+3b)x + 12 = 6x^2 + cx + 12
Then equate the corresponding coefficients
ab = 6 .... x^2 terms4a+3b = c .... x termsWe'll use the fact that a+b = 5. Solving for 'a' gets us a = 5-b
Plug this into the equation dealing with the x^2 coefficients.
ab = 6
(5-b)b = 6
5b-b^2 = 6
0 = b^2-5b+6
b^2-5b+6 = 0
(b-3)(b-2) = 0
b-3 = 0 or b-2 = 0
b = 3 or b = 2
If b = 3, then a = 5-b = 5-3 = 2
If b = 2, then a = 5-b = 5-2 = 3
Therefore, the solutions to this system of equations
[tex]\begin{cases}a+b = 5\\ab = 6\end{cases}[/tex]
are (a,b) = (2,3) and (a,b) = (3,2)
In other words, the answer to the question "what two numbers multiply to 6 and add to 5?" is "2 and 3". The order doesn't matter which is why we can flip the 'a' and b values.
---------------------------------
Go back to 4a+3b = c which was us equating the x coefficients.
This is the same as c = 4a+3b
Plug in a = 2 and b = 3
c = 4a+3b
c = 4*2+3*3
c = 8 + 9
c = 17 is one possible value of c.
Now let's plug in a = 3 and b = 2
c = 4a+3b
c = 4*3+3*2
c = 12 + 6
c = 18 is the other possible value of c.

Miguel bought snacks for his team's practice. He bought a bag of popcorn for $3.33 and a 20-pack of juice bottles. The total cost before tax was $23.33. How much was each bottle of juice?

Given:
A bag of popcorn costs $[tex]3.33[/tex]Miguel bought [tex]20[/tex]packs of juice bottlesThe total cost before tax was $[tex]23.33[/tex]To find: Cost of each bottle of juice?
It is given that Miguel bought snacks for his team's practice which includes a bag of popcorn, and [tex]20[/tex] packs of juice bottles out of which the bag of popcorn cost him $[tex]3.33[/tex] , and the total cost before tax of all the items costs him $[tex]23.33[/tex]
Now we have to find that how much each bottle of juice costs him as asked in the given question.
Let the bag of popcorn's amount be x and the pack of bottle juice is y
Now according to the linear equation in two variable
[tex]x*1+y*20=23.33[/tex]........(1)
where 1 is the total pack of popcorn bag and [tex]20[/tex] the amount of bottle juice packs
As we know that [tex]x=3.33[/tex] since a bag of popcorn costs him $[tex]3.33[/tex]
Now put the value of x in (1) hence,
[tex]3.33*1+y*20=23.33[/tex]
On further solving we get,
[tex]20y=20[/tex]
On further solving we get,
[tex]y=1[/tex] as the price of every juice of bottle.
Hence a bottle of juice costs him $[tex]1[/tex]

The circle is found to have the more area as compered to the square.
What is termed as the perimeter?A perimeter is a loop that encompasses, encircles, or outlines a two-dimensional shape or length. The circumference of a circle or perhaps an ellipse is its perimeter.For the given question;
The length of the wire is given as 22 cm.
The wire is bent in the circle.
Then, the perimeter of the circle is 22 cm.
Perimeter = 2πr = 22 cm.
Where, π = 3.14 and r is the radius of the circle.
2πr = 22 cm.
r = 11/π 11/3.14
The area of the circle is found as;
Area = πr²
Put the values.
Area = 3.14(11/3.14)²
Area = 38.53 cm².
For the square.
Perimeter = 4 side
22 = 4 side
side = 22/4 = 11/2 = 5.5
Area of square = side²
Area of square = 5.5²

The linear equation that models the average price of a new home in terms of the year x is given by y = -5600x + 294000 and the average price of a new home would be $238000 in 2014.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The line must pass through points (0, 294000) and (7, 288400) which is given in the question.
We have to determine the slope of the line :
m = (y₂ - y₁)/(x₂ -x₁ )
m = (288400- 294000)/(7 -0)
m = -5600
This represents new home per year
So with your y-intercept of 294000, your equation becomes
y = -5600x + 294000
Using this equation to predict the average price of a new home in 2014.
Let y be the average price of a new home in the year x, where x = 0 represents the year 2004.
Substitute the value of x = 10 for the year 2014
y = -5600(10) + 294000
y = -56000 + 294000
y = 238000
Hence, the average price of a new home would be $238000 in 2014.
