Step-by-step explanation:
took the test
The expression is equivalent to (n² - 7n + 12) is (n-4)/ (n+4).
The correct option is D.
What is Expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:
Expression: (Math Operator, Number/Variable, Math Operator)
We have,
(n² - 7n + 12) / (n-3)(n+4)
So, Factorizing (n² - 7n + 12)
= (n² -3n - 4n +12)
= n(n-3)- 4(n-3)
= (n-3)(n-4)
Then, (n² - 7n + 12) / (n-3)(n+4)
= (n-3)(n-4)/ (n-3)(n+4)
= (n-4)/ (n+4)

Is 3.13 greater than 3.12
Answers
Answer:
yes
Step-by-step explanation:
if we figure out the difference between the two numbers by subtracting one from the other, if the product comes out positive, then the number you subtracted from is greater, if the product comes up negative, then the number you subtracted from is lesser
say we did 3.13 as our first number
3.13 - 3.12 = 0.01
this means that 3.13 is greater by 0.01, if we switch the two numbers however...
3.12 - 3.13 = -0.01
then that means that 3.12 is lesser by 0.01
i hope this makes sence, working with decimals may get tricky sometimes lol
Yes, 3.13 is greater than 3.12.
What is decimal?A decimal number is a number in which whole number part is separated from a decimal.
How to find greater number?We have been given two numbers 3.13 and 3.12 and we have to find the greater number from these two numbers. When two numbers are in decimal then firstly we have to see the digit before the decimal, the number having large digit becomes large. If the digit before decimal is same in both numbers then we have to see whether the first digit after the decimal is greater or not. If this digit is also same then we will move towards left and so on.
In the numbers 3.12 and 3.13, 3 which is second digit after decimal is greater than 2. So 3.13 is greater than 3.12.
Hence 3.13 is greater than 3.12.

angles sum: 180(6-2) = 720
50 + 37 + 42 = 129
129 + 5x + 7x - 1 + 3x + 40 = 720
15x + 168 = 720
15x = 552
x = 36.8
check:
129 + 5(36.8) + (3(36.8) + 40) + (7(36.8) - 1) = 720
Correct answer??
180-50 = 130
180-37 = 143
180-42 = 138
Known internal angles:
130 + 143 + 138 = 411
15x + 39 + 411 = 720
15x = 270
x = 18

Find the value of the variable
Answers
Answer:
x=6
Step-by-step explanation:
I would look at this triangle and notice that x can be solved by setting up a ratio.
I generally put the short side of the triangle on the top and the long side on the bottom
4/x = x/9
You then cross multiply to get 36=x^2, or +-6=x
A length of a triangle cannot be negative, so we are left with the answer x=6
