The length of a rectangle is 20 units more than its width. The area of the rectangle is x4−100
Answer:
x2−10 because the area expression can be rewritten as (x2−10)(x2+10) which equals (x2−10)((x2−10)+20).
Step-by-step explanation:
Step-by-step explanation: The area of the rectangle is , which can be factored as , because it's the difference of two perfect squares. But, we know that , where is the length and is the width.
Evaluate the limit of sequence at infinity.
[tex] \displaystyle \large{ \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} }[/tex]
Please show your work too. Thanks!
Answer:
[tex]\displaystyle \frac{ 1 }{3} [/tex]
Step-by-step explanation:
we would like to compute the following limit:
[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} [/tex]
if we compute the limit from numerator to denominator directly,we'd end up with
[tex] \dfrac{ \infty }{ \infty } [/tex]
which is an indeterminate form so we must do it in a different way. well to compute this limit,we can consider factoring method . notice that we can factor the numerator and that yields
[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{ {n}^{2} ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]
remember that ,
[tex] \sqrt{ab} \implies \sqrt{a} \sqrt{b} [/tex]thus we acquire:
[tex]\displaystyle \lim_{n \to \infty } \frac{ {n} \sqrt{ ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]
reduce fraction:
[tex]\displaystyle \lim_{n \to \infty } \frac{ {} \sqrt{ 4 {}^{} + \frac{3}{n} } }{6} [/tex]
as n approaches to ∞ ,3/n approaches to 0 which yields:
[tex]\displaystyle \frac{ \sqrt{ 4 {}^{} } }{6} [/tex]
simplify square root:
[tex]\displaystyle \frac{ 2 }{6} [/tex]
reduce fraction:
[tex]\displaystyle \frac{ 1 }{3} [/tex]
hence,
[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} = \boxed{ \frac{1}{3} }[/tex]
and we're done!

Slope = Y2-Y1/X2-X1 = 1-(-5)/1-(-3) = 6/4 = 3/2
THE ANSWER IS
[tex] \frac{3}{2} [/tex]
Answer:
collinear means the points are on the same line
Step-by-step explanation:
we pick any 2 points on the line we need to find its slope
we have p1 (1 ,1) p2 (3,4)
slope = ((y2-y1)/(x2-x1))
= (4-1)/(3-1)
= 3/2

find a counter example to show that each of these statements are false
If the difference between two numbers is odd,
then the two numbers are both odd.
Step-by-step explanation:
let's say, 7 - 4 = 3
that contradicts the statement that both numbers are odd.
no, they are 7, 4, with 4 being even (and not odd).
in fact, as with sums and subtractions in general, it requires an odd and an even number to produce an odd result.
odd with odd always delivers an even result. as does even with even.
solve thefollowing
a) 2(x + 3) = x - 4

How many solutions does this equation have?
4b – 4b = 0
no solution
one solution
infinitely many solutions
The answer is infinitely many solutions because 0 = 0.
If you don't seem to see where I got 0 = 0, look at the equation,
4b – 4b = 0
first lets do the math on the left side.
4b - 4b is equal to 0.
so lets put 0 on the left side, now lets look at the equation all together,
0 = 0,
and this means that it has infinitely many solutions.
The reason why it is not no solution because no solution means when there are no answers to the equation. For example, the solution is not true, such as the equation 24 ≠ 29. This is a no solution equation. One solution can be 4x = 20, as x = 5, concluding it being one solutions.

Answer:
2nd option
Step-by-step explanation:
Given
2x - 6 = 22 ( isolate the x- term by adding 6 to both sides )
2x = 28 ( divide both sides by 2 )
x = 14
Answer:
Add 6 to both sides, then divide by 2. The solution is x = 14
Step-by-step explanation:
Add 6 to both sides:
[tex](2x - 6) + 6 = 22 + 6 \\ 2x = 28[/tex]
And then divide by 2:
[tex] \frac{2x}{2} = \frac{28}{2} [/tex]
The solution is 14
[tex]x = 14[/tex]
Can someone explain how 8.75 multiplied by 0.8 is 7??? It just don't make sense... I don't see why the number got smaller instead of bigger.....
Answer:
80% of 8.75=7. I'm pretty sure this is the reason.
Answer:
It's because of the decimal of .8
Step-by-step explanation:
It can be confusing but since its not a whole number when you multiply with a whole number gets smaller instead of bigger. So the whole number basically has to give some of it to the decimal so, that the outcome can be a whole number.
Sorry, if this isn't the best!

the total cost of a laptop computer is $1278.24. The local sales tax rate is 7.6% what is the retail price?
Answer:
x = 1187.96
Step-by-step explanation:
Let x = price before tax
tax = x* 7.6%
tax = .076x
The cost of the computer is price before tax plus tax
cost = x + .076x
cost = 1.076x
1278.24 = 1.076x
Divide each side by 1.076
1278.24/1.076 = 1.076x/1.076
x=1187.9553
Rounding to the nearest cent
x = 1187.96

Answer:
x^2-7x+4
Step-by-step explanation:
4x^2 -3^2 is basically 4-3, leaving you with 1.
-3x-4x, you're adding to the negative value of -3x, giving -7x.
-4-(-8), a little tricky at first. a trick that i was taught is if you're subtracting a number with a negative number, treat it as if you're adding, therefore -4-(-8) = -4+8, giving you a positive 4.

A. It is increasing.
B. It is decreasing.
C. It is constant.
Answer:
B. It is decreasing.
Step-by-step explanation:
The X value is the sideways one, and the direction of the line in between the two points listed is going downwards. The value of the line in the graph is decreasing.
Answer: Hey the answer is B It is decreasing
Step-by-step explanation:
Well on the graph at points -1 and 1 we can tell the line is going down, meaning the line is decreasing. Hope this helps :) 229 999 0523
Kelly and Greta are asked to write an equation for the scenario below.
“One person was able to plant 4 trees in the same amount of time that 5 people working together were able to plant 20 trees.”
The girls agree that x represents the number of people working and y represents the number of trees planted. Kelly wrote the equation y = one-fourth x, and Greta wrote the equation y = 4 x. Which person is correct, and why?
Answer:
y=4x
Step-by-step explanation:
Cuz in short, if x is one, y is four, if x is 5, y is 20
Thereford only y=4x is suitable
Answer:
Greta is correct.
Step-by-step explanation:
The variable that is lower in each scenario is the variable that should have a coefficient (unless there are fractions). Greta's equation makes sense because it's saying that in order for the # of trees to = the # of people, you need to multiply x by 4, or 4x.
