The length of rectangle PQRS is expressed as 2x+7. The width of rectangle PQRS is expressed as 3x−4. Which expression describes the area of rectangle PQRS?
A.6x^2
B.6x^2-29x-28
C.6x^2-15
D.6x^2+13x-28
Answers
Answer:
[tex]area = length \times width \\ = (2x + 7)(3x - 4) \\ = (6 {x}^{2} - 8x + 21x - 28) \\ = (6 {x}^{2} + 13x - 28) \: sq \: units[/tex]
The area of the rectangle PQRS is given by the formula D) 6x²+13x-28.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
The area of a rectangle is given by the formula:
A = l × w, where l is the length and w is the width.
In this case,
The length is 2x + 7 and the width is 3x - 4.
Therefore, the area of the rectangle is:
[tex]A = (2x + 7)(3x - 4)\\A = 6x^2 - 8x + 21x - 28\\A = 6x^2 + 13x - 28[/tex]
Therefore, the expression that describes the area of rectangle PQRS is D) 6x²+13x-28.

Which image shows a translation?
Answers
Answer:
The option C
Step-by-step explanation:
In the option A and B the image is been showed in either up-side down or mirror image. Only the option C has the image in a correct way and just moved the shape in a different position
The solution is Option C.
The image which shows a translation is Figure C.
What is Translation?
A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
Given data ,
Let the figure be represented as F
Now , the figure is translated up , down, or from side to side
The size of the figure does not change on translation
a)
The figure A has been inverted and it is not a transformation of translation
So , the Figure A is false
b)
The Figure B has been reflected by a factor , and reflection changes the coordinates of the figure F
So , Figure F is False
c)
The Figure C is translated by a factor of x to the left and y to downwards
The size of the figure remains the same
So , Figure C is a translation of Figure F
Hence , the figure C is a translation

Based on the given information, find the measure
of arc DC. (Hint: Try to find angle DBC first.)
Answers
Answer:
122degrees
Step-by-step explanation:
Since triangle BDC is a triangle, hence;
49 + 70 + <DBC = 180
<DBC = 180 - (70+49)
<DBC = 180 - 119
<DBC = 61
Since angle at the vertex is half the angle of its intercepted arc, then;
<DBC = 1/2 x
61 = 1/2 x
x = 61 * 2
x = 122degrees
Hence the measure of arcDC is 122degrees

Esme earns a net salary of $2,400 per month. She already has a savings account that has $100 in it. After paying her expenses every month, she'll be able to add $100 to her savings account. Esme also plans to purchase a car priced at $20,000 using a no-interest loan. She will make a $300 payment on the loan every month. In how many months will Esme have enough money saved to pay off her loan completely?
Answers
Answer:
She will be able to pay off her loan completely in approximately 50 months
Step-by-step explanation:
The amount Esme earns as net salary = $2,400
The amount she already has in a savings account = $100
The amount she would be able to add to her savings account every month = $100
The cost of the car Esme plans to purchase on the no interest loan, A = $20,000
The amount she will make as payment on the loan every month, P = $300 per month
Let 'x' represent the number of month Esme will be able to pay off her loan completely, we have
The number of month Esme will have enough money to pay off her loan completely is given by the following equation;
20,000 = 100 + 300 × x + 100 × x = 100 + 400·x
∴ x = (20,000 - 100)/400 = 49.75
Therefore, the number of months she will be able to pay off her loan completely = 49.75 months ≈ 50 months.

What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
A boat leaves the dock and travels 7 miles due south, then 24 miles due west which is given in the question.
According to Pythagoras's theorem,
In a right-angled triangle, "the square of the hypotenuse is equal to the sum of the squares of the other two sides."
perpendicular²+base²=hypotenuse²
The hypotenuse = c
Here , perpendicular = 7 and base = 24
⇒ 24² + 7² = c²
⇒ 576 + 49 = c²
⇒ 625 = c²
⇒ c² = 625
⇒ c = 25
Therefore, the boat is a distance of 25 miles far away from the dock.

The Atlanta Braves baseball team has a mean batting average of 250 with a standard deviation of 20. Assume the batting averages are approximately normally distributed.
What percent of Braves players fall between 230 and 270?
Answers
Answer:
68 %
Step-by-step explanation:
Since we have our mean x = 250 and standard deviation σ = 20, we need to find how many standard deviations away the values 230 and 270 are.
Note x - σ = 250 - 20 = 230 and x + σ = 250 + 20 = 270
The values are one standard deviation away.
So, the values between 230 and 270 lie in the range x - σ to x + σ.
Since the batting averages are approximately normally distributed and for a normal distribution, 68 % of the values lie in the range x - σ to x + σ.
So, 68 % of Braves players fall between 230 and 270.
What is the discontinuity and zero of the function f(x) = the quantity of 3 x squared plus x minus 4, all over x minus 1 ? (Radical Expressions)
Discontinuity at (−1, 1), zero at ( four thirds , 0)
Discontinuity at (−1, 1), zero at ( negative four thirds , 0)
Discontinuity at (1, 7), zero at ( four thirds , 0)
Discontinuity at (1, 7), zero at ( negtive four thirds , 0)
Answers
Answer:
Discontinuity at (1, 7), zero at (-4/3 , 0)
Step-by-step explanation:
[tex]3x^{2} + x - 4[/tex] = (3x + 4)(x - 1) = 0
x = -4/3 or 1
But x = 1 makes f(x) undefined, so there is discontinuity at x = 1
and there is a zero at x = -4/3.
3x + 4 = 3(1) + 4 = 3 + 4 = 7
If you were to graph this function, then you would get the line y = 3x + 4 with a hole at (1, 7). The line would cross the x-axis at (-4/3, 0) with discontinuity at (1, 7)

P IS A RECTANGLE WITH A LENGTH OF 80 AND WIDTH OF X.Q IS A RECTANGLE WITHA A WIDTH OF 9.THE LENGTH OF Q IS 25 %MORE THEN THE LENGTH OF P.AREA OD Q IS 20% LESS THEN THE AREA OF P.WORK OUT THE RATIO OF X;Y
Answers
Answer:
X:Y = 3/20
Step-by-step explanation:
Given -
Length of rectangle P = 80
Width of rectangle P = X
Length of rectangle Q, Y = 25% more than the length of rectangle P
Length of rectangle Q = 1.25 X
Width of rectangle Q = 9
Area of rectangle P = 80X
Area of Q = 0.75 % of area of rectangle P
Area of Q = 0.75 * 80X = 60 X
or 9Y = 60 X
X:Y = 9/60
X:Y = 3/20
