The arithmetic property used to rewrite the numeric statement is:
A. Associative property of addition
The statement is:
( 6 + 3 ) + 21 − 8 = 6 + ( 3 + 21 ) − 8
In it, the order of the parenthesis is changed, which is the associative property of addition, which states that changing the grouping(order of parenthesis) of the terms does not change the sum.
Hence, the correct option is A.

find all complex solutions of 13x^2-5x+1=0
btw it doesn’t let me do the +- sign
Answer:
Step-by-step explanation:
You can make it by using division +/-. The keystrokes are
+
/
-
a = 13
b = -5
c = 1
x = [-(-5) +/- sqrt( (-5)^2 - 4*13*1) )] / 2
x = [ 5 +/- sqrt( 25 - 52) ] / 2
x = [ 5 +/- sqrt(-27)]/2
x = [5 +/- 3 sqrt(3)i ] / 2
x = 5/2 +/- 3/2 * sqrt(3) i
So x1 = 2.5 + 1.5 sqrt(3)i or
x2 = 2.5 - 1.5 sqrt(3)i

Answer:
80a²b³c
Step-by-step explanation:
As with numbers, the LCM is the product of the highest-powered factors.
16ab³ = 2⁴×a×b³
5a²b² = 5×a²×b²
20ac = 2²×5×a×c
The highest power of the factor 2 is 2⁴.
The highest power of the factor 5 is 5.
The highest power of the factor a is a².
The highest power of the factor b is b³.
The highest power of the factor c is c.
The LCM is 2⁴×5×a²×b³×c = 80a²b³c

29 + 9x ≤ 65
solve for x
Answer:
x <= 4
Step-by-step explanation:
29+9x<65
-29. -29
9x<36
divide both sides by 9
x less than or equal to 4
Answer:
x ≤ 4
Step-by-step explanation:
29 + 9x ≤ 65
subtract 29 from both sides
29 - 29 + 9x ≤ 65 - 29
9x ≤ 36
divide both sides by 9
9x / 9 = x and 36 / 9 = 4
we're left with x ≤ 4

Find the area of the circle. Round to the nearest
tenth. Do not write units of measure.
Find the area of each circle. Use 3.14 for pi.
Answer:
452.16 cm
28.26 m
113.04 km
Step-by-step explanation:
The equation for area is r^2 π
where you square the radius and multiply by 3.14 or pi or how many digits you need to use.
For example, on the first question, you multiply the radius (12) by itself or square it to get 144.
Then you multiply 144 by 3.14 to get your first answer.

This week Sally withdrew $35 from her bank account and deposited $90 into her bank account. Overall, how much did she add to her bank account.
Answer:
55
Step-by-step explanation:
Hailey is 4 more than twice her son Silas's age and 2 years younger than her brother Mark. Which equation shows Silas's age, S, in terms of Mark's age, M?
OS 2+2M
OS-6+4M
os-
OS-
Answer:
H = 2S+4
H = M-2
M-2 = 2S+4
M-6 = 2S
M-6/2 = S
The equation that shows Silas's age, S, in terms of Mark's age is
S = (M - 6)/2.
Option D is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Silas's age = S
Mark's age = M
Hailey's age = H
Now,
H = 2S + 4
H = M - 2
This means,
2S + 4 = M - 2
2S = M - 2 - 4
2S = M - 6
S = (M - 6)/2
Thus,
Silas's age is (M - 6)/2.

Please give me answer!
Answer:
There is no solution to this equation.
Hope this helps :)
Answer:
no solution.
Step-by-step explanation:
carry the -5 and - sign and multiply the numbers within the () signs. so - 5×x and -5×6. which is -5x + -30. the other side will be -5x + 9. so then if you take away the -5x your left with -30 = 9 which is impossible.
Morgan Office Supply sells 8 reams of Brand X paper for $40 and 4 reams of Brand Y paper for $19. What is the cost savings per ream of paper for the cheapest brand?
Answer:
$0.25 per ream
Step-by-step explanation:
The costs per ream are ...
X: $40/(8 reams) = $5/ream
Y: $19/(4 reams) = $4.75/ream
The savings per ream is $5.00 -4.75 = $0.25 for the cheapest brand.

If [tex]a\ \textless \ b[/tex], there are three ordered pairs of positive integers [tex](a,b)[/tex] that satisfy [tex]a^{2}+b^{2}=10(123)^{2}[/tex] If two of these ordered pairs are [tex](39,387)[/tex] and [tex](201,333)[/tex]. What is the third such ordered pair?
The third ordered pair positive integers that satisfies the equation is (123, 369).
The given parameters;
[tex]a^2 + b^2 = 10(123)^2[/tex]First pair of the equation, = (39, 387)Second pair of the equation = (201, 333)The third ordered pair of the equation can be determined by using general equation of a circle;
[tex]a^2 + b^2 = r^2\\\\a^2 + b^2 = (123\sqrt{10} )^2\\\\a^2 + b^2 = (\sqrt{151290} )^2\\\\a^2 + b^2 = 151290\\\\a^2 = 151290- b^2\\\\ a= \sqrt{151290 - b^2}[/tex]
The radius of the circle is calculated as;
[tex]r^2 = 151290\\\\r = \sqrt{151290} \\\\r = 388.96[/tex]
The value of a can be obtained by randomly choosing numbers less than the radius as values of b.
[tex]b < r\\\\b < 388.96[/tex]
[tex]a = \sqrt{151290 \ - \ (387)^2} \\\\a = 39\\\\(39, \ 387)\\\\a = \sqrt{151290 \ - \ (333)^2}\\\\a = 201\\\\(201, \ 333)\\\\a = \sqrt{151290 \ - \ (369)^2}\\\\a = 123\\\\(123, \ 369)[/tex]
Thus, the third ordered pair positive integers that satisfies the equation is (123, 369).
