Step-by-step explanation:
Expanding the first term, we find 1/x at 10(kx)²(1/x)³ = 10k²/x
Expanding the first term, we find 1/x at 8*1⁷(-2/x)¹ = -16/x
Then
10k² - 16 = 74

Solution:
Note that:
Surface area: 2(LB) + 2(BH) + 2(LH)Substitute the values given into the expression to find the surface area.
2(7 x 10) + 2(6 x 6) + 2(6 x 10)=> 2(70) + 2(36) + 2(60)=> 140 + 72 + 120=> 332 mm²The surface area of the rectangular prism is 332 mm².
Length = 6 mm
Height = 7 mm
Width = 10 mm
We know that,[tex] \boxed{\rm Surface\:area\:of\:rectangle=2(LB)+2(BH)+2(HL)}[/tex]
Plug in the given values!~[tex] \sf \nrightarrow \: SA = 2 \times (6 \times 10) + 2 \times (7 \times 10) + 2 \times (6 \times 7)[/tex]

Boardman's Department Store sells clothing for children and adults. Last weekend the store sold 5 adult shirt's for every 3 children's shirts.
If the store sold 30 more adult shirts than children's shirts last weekend, how many shirts the the store sell?
a = adult shirts sold
c = children shirts sold
we know the store sold for every 5 "a", there were 3 "c" sold, so we can say that the adult to children shirts are on a 5 : 3 ratio.
We also know that whatever "c" is, adult shirts sold last weekend was 30 more than that, or namely "c + 30".
[tex]\stackrel{\textit{\large ratios}}{\cfrac{\stackrel{adult}{a}}{\underset{children}{c}}~~ = ~~\cfrac{5}{3}}\qquad \implies \qquad \stackrel{\textit{we also know that \underline{a = c + 30}}}{\cfrac{c+30}{c}~~ = ~~\cfrac{5}{3}} \\\\\\ 3c+90=5c\implies 90 = 2c\implies \cfrac{90}{2}=c\implies \boxed{45=c}~\hfill \stackrel{c + 30}{\boxed{a=75}} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{total~sold}{120}~\hfill[/tex]

What is the total number of possible 4-letter arrangements of the letters
m, a, t, h, if each letter is used only once in each arrangement?
Answer: 24
Step-by-step explanation:
The first letter can be any of the four letters, after that, the second now has 3 letter choices as one of them is used for the first letter, the third has 2 and the fourth has 1. So the total possible arrangements is 4 x 3 x 2 x 1 = 24

A wool suit, discounted by 75% for a clearance sale, has a price tag of $165. What was the suit's original price?
Answer:
$1,100
Step-by-step explanation:
Since we that 75% less than the original price, or 15% of the original price*, is equal to $165, we can set up an equation like this, where [tex]x[/tex] represents the original price:
[tex].15x=165[/tex]
Now, just solve for [tex]x[/tex] by dividing both sides by .15, the equivalent of 15%:
[tex]x=\frac{165}{.15}\\x=1100[/tex]
Therefore, the original price of the suit was $1,100.
*The reason that we use .15 instead of .75 is that when something is on sale with 75% of the original price cut off, 15% of the original price remains. That's why [tex].15x=165[/tex].

To multiply fractions through the following steps:
Multiply the numerators.
Multiply the denominators.
Reduce the resultant fraction to its lowest terms.
Now,
1/4 × 8 = (1 × 8) / 4 = 8/4 = 2
Thus, our answer is 2
Number of slices Dominick ate = 2

Aaliyah is making up 16 party bags for her younger sister's birthday party.
Aaliyah wants to put toys and sweets into the bags in the ratio 5:2.
She has 80 toys. How many sweets does she need?
Answer: 32 sweets
[] The ratio 5:2 goes in the word "toys and sweets" as it is said in the sentence.
-> 5 toys for every 2 sweets
[] We know we will have 16 bags in total. She has exactly enough toys
-> 16 bags in total * 5 toys per bag = 80 toys
[] Because of this, we can multiply 2 by 16 to see how many sweets will be needed.
-> 16 bags in total * 2 sweets per bag = 32 sweets

Solve: 5|x|+6≥1. Write your solution in interval notation.
Answer:
5|x|+6>1=7.5
Step-by-step explanation:
i hope this helped
Answer: x >= -6.2
Step-by-step explanation:
Simplify this first by dividing each side by 5
5|x|+6>/5=1/5
|x| + 6 ≥ 0.2
Since this is an absolute value inequality, we need to setup two inequalities
x+6 >= 0.2
x+6 >= -0.2
Solve Equation 1 → x+6 >= 0.2
Subtract - 6 from both sides of the inequality
x+6 - 6>= 0.2 - 6
x ≥ - 5.8
Solution to absolute value equation 1 is
x >= -5.8
Solve Equation 2 → x+6 >= -0.2
Subtract - 6 from both sides of the inequality
x+6 - 6>= -0.2 - 6
x ≥ - 6.2
