Answer:
2,976
Step-by-step explanation:
I'm not sure if your question has to add all these answers up, but if so... than your answer should be 2,976. That's only if you are adding all of them up. Which is what is sort've looks like.
Answer:
Option D, I agree with neither Elena nor Lin
Step-by-step explanation:
The remaining part of the question is attached herewith
Solution
As we can see in the image
ED is perpendicular to AB and BC is perpendicular to AB
Thus, as per the Pythagoras theorem,
AC^2 = AB^2 + BC^2
14^2 = 6^2 + BC^2
BC^2 = 196-36 = 160
BC = 12.649 OR 12.65
Hence, option D
I agree with neither Elena nor Lin
The answer is 2√5

Answer:
Mary-15
Joan-9
Step-by-step explanation:
1) create an equation with the information given:
x•(x+6)=135
2) using this create a quadratic equation by distributing and getting all the terms to one side:
y=x²+6x-135
3) finally use the quadratic formula, ((-b)±√(b²-(4•a•c)))/(2•a)
4) using this you will find the value for Joan's age. Add six to Joan's age to find Mary's
5) You can check your answer by multiplying them to see if they equal 135.
If the function is f(x)=1/(6x+6) then the value of x cannot be equal to -1.
Given a function of x f(x)=1/(6x+6).
We are told to find out the value of the variable x for which the function does not lie.
Function is like a relationship between two or more variables expressed in equal to form. The values entered in a function is known as domain and the values which we get after entering of values are known as range.
f(x)=1/(6x+6)
It is in form of fraction. Fraction is a combination of numbers in which the above number is numerator and below number is denominator.
In this (6x+6) cannot be equal to 0 because if (6x+6) equal to 0 then the value of function becomes infinity.
So,
6x+6=0
6x=-6
x=-1
Hence if the function is f(x)=1/(6x+6) then the value of x cannot be equal to -1.
