A rectangle has an area of 40 square units. The width of the rectangle is (n+3) and the height is n. Find the value of n.
Answer:
(n+3) × n =40
n^2 + 3n =40
n^2 + 3n - 40=0
(n+8)(n-5)=0
n=-8 or n=5
Find the slope of the line that passes through points (10,2) and (3,5)
Answer:
Slope = -3/7
Step-by-step explanation:
The formula for slope is y2-y1/x2-x1.
Substitute for the points.
5-2/3-10 = -3/7
Answer:
-3/7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-2)/(3-10)
m=3/-7

Which statement about f(x) = 2x2 – 3x - 5 is true?
A The zeros are - and -1, because f(x) = (x + 1)(2x + 5).
2
5
B The zeros are - and 1, because f(x) = (x - 1)(2x + 5).
2
C The zeros are -1 and, because f(x) = (x + 1)(2x-5).
The zeros are 1 and, because f(x) = (x - 1)(2x - 5).
9514 1404 393
Answer:
C. The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).
Step-by-step explanation:
The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.
The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.
Additionally, the x-term needs to match the result of multiplying out the factors.
B. (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)
C. (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)
The factors of C are zero when x=-1, x=5/2.

On the first day of your garage sale, you earned 129x+ dollars. The next day you earned 22x dollars. Is it possible that you earned the same amount each day? Explain.
Answer:
Yes, it is possible
Step-by-step explanation:
It is possible because X does on the second day could be negative. It's a simple question, and you don't need to figure out the answer.
Basically, X on the second day could be a negative OR positive answer.
Ech morning papa notes the brids feedings on his birdfeeder. So far this month he has seen 59 blue jays 68 black crows and 12 red robins and 1 cardinal. If 300 birds visit papa's birdfeeder, how many blue jays can we expect to see
Answer:
126
Step-by-step explanation:
Total number of birds already observed: 59 + 68 + 12 + 1 = 140
Number of blue jays observed: 59
Fraction of blue jays: 59/140
Number of blue jays expected in 300 birds:
59/140 * 300 = 126
Answer: 126
Solve 5x - 9 = 2x + 3
Answer:
x=4
Step-by-step explanation:
Simplifying
5x + 9 = 2x + -3
Reorder the terms:
9 + 5x = 2x + -3
Reorder the terms:
9 + 5x = -3 + 2x
Solving
9 + 5x = -3 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
9 + 5x + -2x = -3 + 2x + -2x
Combine like terms: 5x + -2x = 3x
9 + 3x = -3 + 2x + -2x
Combine like terms: 2x + -2x = 0
9 + 3x = -3 + 0
9 + 3x = -3
Add '-9' to each side of the equation.
9 + -9 + 3x = -3 + -9
Combine like terms: 9 + -9 = 0
0 + 3x = -3 + -9
3x = -3 + -9
Combine like terms: -3 + -9 = -12
3x = -12
Divide each side by '3'.
x = -4
Simplifying
x = -4

A Notebook cost $5.50 plus sales tax after sale tax the notebook is $5.83 what is the sale tax rate?
$5.83-$5.50
=$0.33 tax rate charged
Answer:
6%
Step-by-step explanation:
5.83 - 5.50 = .33 sales tax
Sales price x sales tax rate - sales tax
5.50 x sales tax rate = .33
sales tax rate = .33/5.50
sales tax rate = .06 or 6%

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adults.The receipts for admission totaled to $1249.50. How many children and how many adults swam at the public pool that day?
Answer:
120 children and 388 adults bought tickets for the swimming pool
Explanation:
Create two simultanous equations:
Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being
c
+
a
=
508
then, you now create a second equation for the prices of the tickets.
(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected
so:
1.75
c
+
2.25
a
=
1083.00
now we still know, that
a
=
508
−
c
so we can substitute it into the second formula
1.75
c
+
2.25
(
508
−
c
)
=
1083
now its just simple algebra
1.75
c
+
1143
−
2.25
c
=
1083
60
=
0.5
c
so:
c
=
120
now we know, that 120 children went to the swimming pool.
and we still have the formula from before:
a
=
508
−
c
so
a
=
388
The measure of ZB is (3x – 4) and the measure of
ZD is (2x - 6)". What are the measures of angles B
and D?
mZB=
mZD =
The measure of <B and <D are 110 degrees and 70 degrees
What is Circle geometry?The sum of the opposite angle of the quadrilateral within the circle is 360 degrees.
Given the following parameters
<B = 3x - 4
<D = 2x - 6
Equate both equations
<B + <D = 180
3x - 4 + 2x - 6 = 180
5x - 10 = 180
5x = 190
x = 190/5
x = 38
Determine the measure of <B and <D
<B = 3x - 4 = 3(38) - 4
<B = 110 degrees
<D = 2x - 6
<D = 2(38) - 6
<D = 76 - 6
<D = 70 degrees
Hence the measure of <B and <D are 110 degrees and 70 degrees

How to find the missing side of this triangle
The product of 8 and c is 72.
Answer: If your asking what c is its 9
Step-by-step explanation: How I did it was I did 72/8, which is 9. How I checked was I did 8*9 and I got 72
C is 9 if you multiply 8 and c to get 72.
THREE expressions equivalent to –81x+27.
Hey there!
One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us [tex]\frac{-81x+27}{3}[/tex]. If we simplify this, we get [tex]-27x+9[/tex].
Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us [tex]\frac{-81x+27}{21}[/tex]. If we simplify this, we get [tex]-3x+1[/tex].
One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us [tex]1(-81x+27)+0[/tex].
Have a terrificly amazing day! :D
