HELP PLEASE!!! The area of a square is (16x2 − 8x + 1) square units. Determine the length of each side of the square by factoring the area expression completely.
Answer:
Length of each side = (4x-1)
Step-by-step explanation:
You could use the Quadratic formula to solve this, but there is a bit of a logical/intuitive gap you have to jump over at the end to get the answer.
For a straightforward mathematical explanation of what the area is equal to, you need to complete the square. From there you acknowledge that a square's sides are equal to each other and then you'll have your lengths.
My work is in the attachment. Comment with any questions.
Answer:
4x - 1
Step-by-step explanation:
given area of square :
16x² − 8x + 1
(4x)² -8x + 1
factor the equation
and this is a perfect square trinomial
a² - 2ab + b² = (a-b) (a-b)
(4x)² - 8x + 1 = (4x-1) (4x-1)
we know that the area A = s² (s stands for side)
substitute, (4x-1)² = s²
4x - 1 = s
therefore, the side of a square s = 4x - 1
What is the least common denominator of the expression below?
g^2 14+g
_____ + _____
9-g^2 24g+8g^2
Greetings from Brasil...
from notable products:
A² - B² = (A + B)·(A - B)
bringing to our problem:
9 - G² = (3 + G)·(3 - G)
Factoring 24G + 8G²:
8G(3 + G)
So, we have:
{G²/[ (3 + G)·(3 - G)]} + {(14 + G)/[8G(3 + G)]}
So the least common denominator is: 3 + G
[tex]\large{\frac{G^2}{9-G^2}+\frac{14+G}{24G+8G^2}=\frac{G^2}{(3+G)\cdot (3-G)}+\frac{14+G}{8G\cdot (3+G)}}[/tex]
Jan owns a coffee shop. She is planning to hire Michael as a part-time employee at $8.50 per hour. She will also contribute $20 each week to a bonus fund, to be paid out at a later date. Michael cannot work more than 35 hours a week. How much will it cost Jan to hire Michael during his first 2-week pay period?
Answer:
635 dolalrs
Step-by-step explanation:
How many hours can Jan work in both weeks
35(2) = 70 hours
70 (8.50) = 595 dollars base salary.
Bonus each for both weeks = 2(20) = 40
595 + 40 = 635 dollars
Answer:
$595
Step-by-step explanation:
8.50x 70 hours= equal pay for 2 weeks without bonus pay
35 plus 35=70 hours
$595 without bonus
2(35x8.5) + 2(20)=636 (with bonus)
Without bonus 2(35x8.50)=595

An ant walked on the coordinate plane from point A( − 3,1) to point B(1,25) by the shortest path. Find y-coordinate of the point where the ant intersected y-axis.
Answer:
19
Step-by-step explanation:
The shortest path is a straight line. The slope of that line is:
m = (25 − 1) / (1 − (-3))
m = 6
The point where the ant intersects the y-axis has an x-coordinate of 0. The slope between that point, and any other point on the line, is 6.
6 = (y − 1) / (0 − (-3))
y = 19

For x different from 5, we can write
[tex]\dfrac{x^2-3x-10}{2x-10}=\dfrac{(x-5)(x+2)}{2(x-5)}=\dfrac{x+2}{2}[/tex]
So, the limit when x tends to 5 is

Which of the following pairs of functions are inverses of each
other?
Answer: C
Step-by-step explanation:
For this problem, let's find the inverse for all f(x) and see which pairs with the g(x). To find the inverse, you replace the x with y and y with x. Then you solve for y.
A. Incorrect
[tex]y=\frac{x-8}{4} +9[/tex] [replace x with y and y with x]
[tex]x=\frac{y-8}{4} +9[/tex] [subtract both sides by 9]
[tex]x-9=\frac{y-8}{4}[/tex] [multiply both sides by 4]
[tex]4(x-9)=y-8[/tex] [add both sides by 8]
[tex]4(x-9)+8=y[/tex]
This does not match g(x), therefore, they are not inverses of each other.
----------------------------------------------------------------------------------------------------------
B. Incorrect
[tex]y=4(x-12)+2[/tex] [replace x with y and y with x]
[tex]x=4(y-12)+2[/tex] [subtract both sides by 2]
[tex]x-2=4(y-12)[/tex] [divide both sides by 4]
[tex]\frac{x-2}{4} =y-12[/tex] [add both sides by 12]
[tex]\frac{x-2}{4} +12=y[/tex]
This does not match g(x), therefore, they are not inverses of each other.
----------------------------------------------------------------------------------------------------------
C. Correct
[tex]y=3(\frac{x}{2})-4[/tex] [replace x with y and y with x]
[tex]x=3(\frac{y}{2} )-4[/tex] [add both sides by 4]
[tex]x+4=3(\frac{y}{2} )[/tex] [divide both sides by 3]
[tex]\frac{x+4}{3} =\frac{y}{2}[/tex] [multiply both sides by 2]
[tex]\frac{2(x+4)}{3} =y[/tex]
This matches g(x), therefore, they are inverses of each other.
----------------------------------------------------------------------------------------------------------
D. Incorrect
[tex]y=3(\frac{2}{x} )-10[/tex] [replace x with y and y with x]
[tex]x=3(\frac{2}{y} )-10[/tex] [add both sides by 10]
[tex]x+10=3(\frac{2}{y} )[/tex] [divide both sides by 3]
[tex]\frac{x+10}{3} =\frac{2}{y}[/tex] [multiply both sides by y]
[tex](y)(\frac{x+10}{3} )=2[/tex] [multiply both sides by [tex]\frac{3}{x+10}[/tex] or divide by [tex]\frac{x+10}{3}[/tex]]
[tex]y=\frac{6}{x+10}[/tex]
This does not match g(x), therefore, they are not inverses of each other.

Hi there! :)
Answer:
[tex]\huge\boxed{BC = 26}[/tex]
In the question, it is given that AB = 3x - 1 and AC = 8x - 20.
Since AB = 3x - 1 and B is the midpoint, this means that BC is also 3x - 1. We can express this as an algebraic equation:
8x - 20 = 2(3x - 1)
Distribute the 2 with terms inside of the parenthesis:
8x - 20 = 6x - 2
Subtract 6x from both sides:
2x - 20 = -2
Add 20 to both sides:
2x = 18
Divide both sides by 2:
x = 9
Solve for BC by plugging in the value of x into the formula for AB
(since AB ≅ BC):
3(9) - 1 = 27 - 1 = 26 units.
BC = 26 units.
Answer:
BC = 5x - 19
Step-by-step explanation:
AC = 8x - 20
AB = 3x - 1
AC = AB + BC
Plug in the corresponding terms to the corresponding variables;
AC = AB + BC
(8x - 20) = (3x - 1) + BC
Isolate the term, BC, subtract 3x - 1 from both sides:
(8x - 20) - (3x - 1) = (3x - 1) - (3x - 1) + BC
BC = 8x - 20 - 3x + 1
BC = 8x - 3x - 20 + 1
BC = 5x - 19

Michael and his sister Mel share the job of mowing the grass in their yard. Michael mows 1/3
of the yard, and Mel mows the rest. Mel can mow 3/4 of the entire yard in an hour. How long will it take Mel to finish mowing her part of the yard?
Answer:
Approximately 53 mins
Step-by-step explanation:
Yard mowed by Michael = ⅓ of the yard
Yard mowed by Mel = 1 - ⅓ = [tex] \frac{1}{1} - \frac{1}{3} = \frac{3 - 1}{3} = \frac{2}{3} [/tex]
Rate at which Mel can mow a yard = ¾ of the yard in 1 hour
That is, it would take 1 hr to mow ¾ of the yard.
If ¾ yard requires 1 hr, then,
⅔ yard would require x hr
Thus:
x*¾ = 1*⅔
[tex] \frac{3x}{4} = \frac{2}{3} [/tex]
Cross multiply
[tex] 3(3x) = 4(2) [/tex]
[tex] 9x = 8 [/tex]
Divide both sides by 9
[tex] x = \frac{8}{9} [/tex]
It would take Mel [tex] \frac{8}{9} hr [/tex] to finish mowing her part, which is approximately 53 mins. [tex] (\frac{8}{9}*60mins = 53.3mins [/tex].

Sam paid $3.60 for 3/4 pound of his favorite trail-mix. What is the unit price (dollars per pound)?
Answer:
So the unit price of the trail - mix is $4.80 per pound
Step-by-step explanation:
Sam paid $3.60 for 3/4 pound of his favorite trail-mix.
What it means is that said paid for 3/4 = 0.75 of a pound for $3.60
So let's determine how much he could have paid for a complete pound
$3.60= 0.75 pound
X= 1 pound
$X*0.75 pound= $3.60*1 pound
$x= ($3.60*1 pound)/0.75 pound
$x=$3.60/0.75
$x= $4.80
So the unit price of the trail - mix is $4.80 per pound
