Step-by-step explanation:
1) Select all the pairs of equivalent expressions.
These are the correct options
d. 4³ ⋅ 5³and 20³
4³ × 5³ = 8000
20³ = 8000
e. (43)3 and 43 ⋅ 43 ⋅ 43
2. Choose an equivalent expression for 12³ • 12⁹• 12⁴• 12².
For an Algebraic Expressions,
We have the rule
x^a × x^b = x ^a+ b
Hence: 12³ • 12⁹• 12⁴ • 12².
= 12^3+9+4+2 = 12^18
Hence, b. 12^18
3. Choose an equivalent expression for

For an Algebraic expressions
x^a ÷ x^b = x ^a - b
Therefore
10⁶÷ 10⁴ = 10²
a. 10^2 Is the correct option

1. There are equivalent expressions in options (a) and (e).(43)3 and 43 ⋅ 43, (43)3 and 43 ⋅ 43 ⋅ 43
2. The equivalent expression for 123 • 129 • 124 • 122 is 12^18. Option b
3. The equivalent expression for 106 ÷ 104 is 10^2.Option a
4. Equivalent expressions in options (a) and (c) represent 78 • 7.
5. The equation 63 ⋅ 73 = 423 is not correct; the correct result is 63 • 73 = 1369.Option C
1. Pairs of Equivalent Expressions:
a. (43)3 and 43 ⋅ 43: These are equivalent expressions because (43)3 means 43 raised to the power of 3, which is the same as 43 multiplied by itself 3 times.
e. (43)3 and 43 ⋅ 43 ⋅ 43: These are equivalent expressions because (43)3 means 43 raised to the power of 3, which is the same as 43 multiplied by itself 3 times.
2. Equivalent Expression for 123 • 129 • 124 • 122:
b. 12^18: This expression represents the product of 12 raised to the power of 18, which is equivalent to multiplying the given numbers.
3. Equivalent Expression for 106 ÷ 104:
a. 10^2: This expression represents 10 raised to the power of 2, which is equivalent to the given division.
4. Expressions Equivalent to 78 • 7:
a. 73 • 73: This expression represents the square of 7^3, which is equivalent to 78 • 7.
c. (73)3: This expression represents 7^3 raised to the power of 3, which is equivalent to 78 • 7.
5. Is the Equation Correct?
C. No; 63 • 73 is equal to (6 • 7 • 3) or (42 • 3). The equation 63 ⋅ 73 = 423 is not correct; the correct result is 63 • 73 = 1369. The provided equation does not accurately represent the multiplication of 63 and 73.

James and Anna walk their dogs every 3 and 4 days respectively. The Least Common Multiple of 3 and 4 is 12, so they will walk their dogs together every 12 days. Since they walk their dogs on a Monday, they will walk them together on a Monday.
This question is about finding the Least Common Multiple (LCM) of two numbers. In this case, the two numbers are the days James and Anna walk their dogs: 3 days and 4 days. The LCM of 3 and 4 is 12. Therefore, James and Anna will walk their dogs together every 12 days.
If they both walk their dogs on a Monday, 12 days later will also be a Monday. So, they will walk their dogs together on the same day of the week, which is Monday.

Answer:
Add each given variable
(6x + 10) + (x + 2) + x = 8x + 12
The sum of all the angles equals 180ᴼ
8x + 12 = 180
Subtract 12 from both sides
8x = 168
Divide by 8 on both sides
x = 21
Now plug in 21 for each x to find the measure of each angle.
(6[21] + 10) = 126 + 10 = 136ᴼ
(21 + 2) = 23ᴼ
x = 21ᴼ
Answer:
-49%
Step-by-step explanation:
i know this one by doing a long math formula
Answer:
49.0%
Step-by-step explanation:
take the 2 numbers and find the difference
51 - 26 = 25
take the difference and divide it by the orginal number
25÷51 = 0.49019607843
then times that number by 100
(25÷51) × 100 = 49.0196078431
so the number was decreased by 49.0 %
