Answer:
For the first section, you write the algebraic expression or equation that goes with the statement.
For example, 9 more than the product of 51 and number "i" would translate into 51i+9. More and sum refers to addition, difference is subtraction, and quotient is division.
For the second section, you just simplify each of the expressions. when a number has ^, that means it has the square root, so 9^2 would be nine squared, which is 81.
For the third section, replace the c values for 3 and the d values for 5.
For the fourth section, determine whether or not each number is rational by writing the number as a fraction where both numerator and denominator are whole numbers. Pi is irrational as it can't be written as the fraction of 2 integers
For the last section, combine like terms and explain each step.
What is the greatest common factor of 42 and 14?
Answers
It is 14 because if you do prime factorization:
14 = 2 x 7
42 = 2 x 3 x 7
They have the factors 2 and 7 in common.
2 x 7 = 14.
Answer:
The GCF is 14!
Step-by-step explanation: Okay Lets multiply to get 42, 14 x 1 is 14, 14 x 2 is 28, 14 x 3 is 42! We also know that this is the GCF because 42 and 14 can both be divided by 14!

Which expression is equivalent to √100 +4√10 +3 −8 √10?
1) −4√10 + 13
2) 10 − √10
3) 3 − 2√10
4) √10
Answers
Answer:
√100 +4√10 +3 −8 √10 = −4√10 + 13 TRUE
Step-by-step explanation:
Simplify the following:
sqrt(100) + 4 sqrt(10) + 3 - 8 sqrt(10)
Hint: | Simplify radicals.
sqrt(100) = sqrt(10^2) = 10:
10 + 4 sqrt(10) + 3 - 8 sqrt(10)
Hint: | Evaluate 10 + 4 sqrt(10) + 3 - 8 sqrt(10).
10 + 4 sqrt(10) + 3 - 8 sqrt(10) = 13 - 4 sqrt(10):

Answers
Answer:
72°
Explanation:
Given that line J and line K are parallel, we can safely assume that line m is the transversal for the following question. We can also remove line l so that we can focus on line m instead.
Using the rule of Alternate Exterior Angle theorem, x would equal to 72°.
Answer: 72
Now that we are told that J and K are parallel, we know that there can be a transversal line (m). You can see that m goes 72 degrees.
So, the answer is 72. Best of Regards!

Given a triangle JLM with vertices J(-4,3), L(-2,7), and M(2,7). What would the coordinates be if it was reflected across the line y=1?
Answers
Answer: M'(2, - 5), L'(-2, -5), j'(-4, - 1)
Step-by-step explanation:
When we do a reflection over a given line, the distance between all the points (measured perpendicularly to the line) does not change.
The line is y = 1.
Notice that a reflection over a line y = a (for any real value a) only changes the value of the variable y.
Let's reflect the points:
J(-4, 3)
The distance between 3 and 1 is:
D = 3 - 1 = 2.
Then the new value of y must also be at a distance 2 of the line y = 1
1 - 2 = 1
The new point is:
j'(-4, - 1)
L(-2, 7)
The distance between 7 and 1 is:
7 - 1 = 6.
The new value of y will be:
1 - 6 = -5
The new point is:
L'(-2, -5)
M(2,7)
Same as above, the new point will be:
M'(2, - 5)
