Veronica is given a rectangular piece of paper. If the length of Veronica's piece of paper is represented by x2 + 6x – 2 and the width is represented by 3x - 5, find the area of the piece of paper.
Answer:
3x^3 +13x^2 - 36x + 10.
Step-by-step explanation:
Area = length * width
= (3x - 5)(x^2 + 6x - 2)
= 3x(x^2 + 6x - 2) - 5)(x^2 + 6x - 2)
= 3x^3 + 18x^2 - 6x - 5x^2 - 30x + 10
= 3x^3 + 13x^2 - 36x + 10.

Which set of ratios below is equivalent to 5:6?
the distance between the two points (-6, 1) and (-4, 5). Round to the nearest tenth.
Answer:
d = 4.5
Step-by-step explanation:
d = [tex]\sqrt{\s(x2-x1)^{2} +(y2-y1)^{2}}[/tex]
d = [tex]\sqrt{(-4+6)^2+(1-5)^2}[/tex]
d = 4.5

Then plug 2 in for x in the first equation to find y. y=0
answer x=y-4/2
Step-by-step explanation:
-4=2x y-4/2=x
x=2+5y
My interior angle of a shape is 50 degrees. What is my EXTERIOR angle that matches my interior angle?
Answer:
130°
Step-by-step explanation:
The interior and exterior angles should be supplementary, meaning they add up to 180°.
180-50=130

A test has a mean of 80 with a standard deviation of 4. Which of the following scores is within one standard deviation of the mean?
A
75
B
77
С
BO
D
90
E
09
Answer:
B
Step-by-step explanation:
Mathematically, we shall be using the z-score here
Z-score = (x-mean)/SD
From the question, mean = 80 and SD = 4
So we want to get the option in the question that has a z-score of 1 or below
Let’s look at 75
80-75 = 5 ( this is clearly above 1 standard deviation of 4)
For 77;
80 -77 = 3
This is less than the standard deviation of 4, meaning it is within 1 standard deviation of the mean
Option B) is correct.
Step-by-step explanation:
Given :
Mean [tex](\mu)[/tex] = 80
Standard Deviation [tex](\sigma)[/tex] = 4
Calculation :
We have to find the score that would be 1 deviation from the mean. Which means, the interval [tex](\mu-\sigma, \mu+\sigma)[/tex]
[tex]\mu-\sigma = 80-4=76[/tex]
[tex]\mu+\sigma =80+4=84[/tex]
The interval is (76,84)
Therefore, option B) is correct.

2x-1+9x+3=57 solve for X
Answer:
x = 5
Step-by-step explanation:
2x-1+9x+3=57
2x+9x=57+1-3
11x=55
x= 55/11
x= 5
Answer:
x = 5
Step-by-step explanation:
Simplifying 2x + -1 + 9x + 3 = 57
Reorder the terms: -1 + 3 + 2x + 9x = 57
Combine like terms: -1 + 3 = 2 2 + 2x + 9x = 57
Combine like terms: 2x + 9x = 11x 2 + 11x = 57
Solving 2 + 11x = 57
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2' to each side of the equation. 2 + -2 + 11x = 57 + -2
Combine like terms: 2 + -2 = 0 0 + 11x = 57 + -2 11x = 57 + -2
Combine like terms: 57 + -2 = 55 11x = 55
Divide each side by '11'. x = 5
Simplifying x = 5

Mario had 12 apples and gave away x apples. Luigi had 26 apples and gave away three times as many apples as Mario did. How many apples did Mario give away if they had the same number of apples left?
Answer:
7 Apples
Step-by-step explanation:
For this question, we can write expressions for Maria's apples and Luigi's apples and form an equation as they end up with the same amount.
Mario starts with 12 apples but gives away x number. This means Mario's final amount of apples can be represented as: 12-x
Similarly Luigi starts with 26 and gives away 3 times the amount of Mario. So the number he gave away can be represented as: 3x (3 times the number Mario gave away). Therefore we can represent Luigi's final number as: 26-3x
Since they both end up with the same number of apples, we can put these expressions equal to each other in an equation to solve for x (the number of apples Mario gave away):
Mario Luigi
12-x = 26-3x
12-x=26-3x
Now we just need to move the unknowns to one side and the other terms to the other, combine and solve:
12-x-12=26-12-3x
-x=14-3x
-x+3x=14-3x+3x
2x=14
2x/2=14/2
x=7
Mario gave away 7 apples.
Hope this helped!

What is the sum of the measures of the interior angles of the decagon?
Given parameters:
Number of sides of the regular body = 10
A decagon has 10 sides.
Unknown:
Sum of the measures of the interior angles = ?
Solution;
To find the sum of the interior angles of a decagon; use the expression below:
Sum of interior angles = (n - 2) x 180
where;
n = number of sides;
So,
Sum of interior angles = (10 - 2) x 180 = 1440°
The sum of interior angle of a decagon is 1440°
A parkingmeter charges$2 perhour.As a driverparks hercar,she noticesthat the parkingmeterhas15 minutesremainingonitfromthe previousdriver whousedthe parking spot.Ifthedriverinsertsd dollarsintotheparkingmeter and theparkingmeter has 3 hoursremainingon itas a result,write an equationtosolve ford?
Answer:
3 = 0.25 + 0.5d
Step-by-step explanation:
Given that:
Amount charged per hour = $2
Time left before inserting $d = 15 minutes
Total time after inserting $d = 3 hours
Total time of 3 hours = time left by previous driver + hours purchased with $d
$2 = 1 hour
$d = x
2x = d
x = d/2 ; 0.5d
Since 15 minutes is left before inserting $d
15 minutes to hour ; 15/60 = 0.25
Total time of 3 hours = time left by previous driver + hours purchased with $
3 = 0.25 + 0.5d
