Factor:
36x2 - 81y2
(6x + 9y)(6x + gy)
(9x - 9y)(4x + 9y)
(6x - 9y)(6x - 9y)
(6x - 9y)(6x + 9y)
Answers
Answer:
D
Step-by-step explanation:
The square root of 36 is 6 and the square root of 81 is 9 so that cancels out the answers C and B then there is a subtraction symbol in the original equation so there has to be one in the answer which cancels our A and leaves you with the final answer D.

Given m<12= 121 and m<6= 75, find the measure of each missing angle.
Answers
Answer/Step-by-step explanation:
Given:
m<12 = 121°
m<6 = 75°
a. m<1 = m<6 (vertical angles)
m<1 = 75° (substitution)
b. m<12 = m<1 + m2 (alternate exterior angles)
121° = 75° + m<2 (substitution)
121° - 75° = m<2 (subtraction property of equality)
46° = m<2
m<2 = 46°
c. m<1 + m<2 + m<3 = 180° (angles on a straight line)
75° + 46° + m<3 = 180° (substitution)
121° + m<3 = 180°
m<3 = 180° - 121° (subtraction property of equality)
m<3 = 59°
d. m<4 = m<3 (vertical angles)
m<4 = 59° (substitution)
e. m<5 + m<4 + m<6 = 180° (angles on a straight line)
m<5 + 59° + 75° = 180° (substitution)
m<5 + 134° = 180°
m<5 = 180° - 134° (Subtraction property of equality)
m<5 = 46°
f. m<7 = m<12 (vertical angles)
m<7 = 121° (substitution)
g. m<8 = m<4 (vertical angles)
m<8 = 59° (substitution)
h. m<9 = m<6 (Alternate Interior Angles)
m<9 = 75° (substitution)
i. m<10 + m<9 = 180° (Linear Pair)
m<10 + 75° = 180° (substitution)
m<10 = 180° - 75° (Subtraction property of equality)
m<10 = 105°
j. m<11 = m<8 (vertical angles)
m<11 = 59° (substitution)
k. m<13 = m<10 (vertical angles)
m<13 = 105° (substitution)
l. m<14 = m<9 (vertical angles)
m<14 = 75° (substitution)

Answers
Answer: 5√10.
Step-by-step explanation:
250 is split into its prime factors as 2 * 5 * 5 * 5 which implies √250 = √(2 * 5 * 5 * 5). Now we can simplify this further by pulling out the number which is multiplied to itself. This gives √250 = 5 * √(2 * 5) = 5√10. Therefore the square root of 250 is √250 = 5√10.

Write the quotient as a power:
Answers
Answer
x^(2) x to the second power
Step-by-step explanation:
To divide exponents (or powers) with the same base, subtract the exponents. Division is the opposite of multiplication, so it makes sense that because you add exponents when multiplying numbers with the same base, you subtract the exponents when dividing numbers with the same base.
For the following equation, find a solution for the variable. Show all of your work and use complete sentences to explain the solving process that you used to find a solution for the equation. Be sure to include at least two terms from the word bank.
6 = 3 x - 9
Answers
Answer:
x=5
Step-by-step explanation:
solution;
6=3x-9(carry alike terms to the same side that'd be +6-9)
+9+6=3x
15=3x(divide both sides by 3)
5=x
(thanks,sorry and welcome)
The solution to the given equation 6 = 3x - 9 would be variable x = 5.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
To determine a solution for the variable in equation 6 = 3x - 9, we can begin by isolating the variable on one side of the equation. To do this, we can add 9 to both sides, giving us:
6 + 9 = 3x
This simplifies to:
15 = 3x
The next step is to divide both sides of the equation by 3, which will give us the value of x.
15/3 = 3x/3
Simplifying we get
5 = x
Thus, the solution for the variable is x = 5.

what is the greatest three-digit multiple of 33 that can be written using three different digits?
Please help me!!!
Answers
Answer:
957Step-by-step explanation:
The largest three-digit multiple of 33 * 30 is 990, which uses only two different digits. Now we work backwards: Subtracting 33 once gives 990-33=957, which has three different digits. Therefore, our answer is 957
957 is the greatest three-digit number which is multiplied by 33.
What are digits?A numerical digit is a single sign that can be used alone or in combination to denote a number in a positional numeral system.
A digit is a component of a set that, when put together, forms a numerical system.
Examples of digits include 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
If we multiply 33 by 31
It gives 1023 which is a four-digit number.
Now trying to multiply less than 31
By 30
33 × 30 = 990 but here two digits are the same.
By 29
33 × 29 = 957 and all three are different.
Hence "957 is the greatest three-digit number which is multiplied by 33".

The distance between two towns is 130 kilometers. There are approximately 8 kilometers in 5 miles.
Which measurement is closest to the number of miles between the two towns?
Please Give A Good Answer Ill Give Brainest And Extra Points
Answers
Answer: 81 miles
Step-by-step explanation:
From the question, we are informed that the distance between two towns is 130 kilometers and that there are approximately 8 kilometers in 5 miles.
The measurement that is closest to the number of miles between the two towns goes thus:
Firstly, we need to divide 130 kilometers by 8 kilometers. This will be:
= 130/8
= 16.25
Then, we multiply 16.25 by 5 to get the number of miles between the two towns. This will be:
= 16.25 × 5 miles
= 81.25 miles
= 81 miles
