<h3>
Answer:</h3>

<h3>
Step-by-step explanation:</h3>
The common ratio is -8/4 = -2. The general formula for the n-th term is ...
... an = a1·r^(n-1) . . . . . . note the use of the caret (^) and parentheses
For r = -2 and a1 = 4, this becomes ...
... an = 4·(-2)^(n-1) . . . . approximately matches the 2nd selection
Answer:
Given: Gables property Corp is leasing office buildings with an area of 
⇒ Area = 
we can write this as:
Area =
.....[1]
Use the identity formula:

then, by using this formula in [1] we have;
Area =
or
Area =
square units
Area of building =
where l is the length and w is the width respectively;
⇒
units
Therefore, the possible length and width of the building is;
l = 7x+5 units
w = 7x+5 units
As we know that the Area of a square is equal to side times side . Since each side of a square is the same, it can simply be the length of one side squared.
Therefore, the possible shape of the building is Square.
Answer:
The average sallary of a Master's is 60 thousand and of a Bachellor's is 53 thousand.
Step-by-step explanation:
In order to solve this problem we first need to attribute variables to the unkown quantities. We will call the average salary of Master's "x" and the average salary of a Bachellor's "y". The first information the problem gives us is:
x = 2*y - 46
The second one is:
x + y = 113
We now have two equations and two variables, so we can solve the system. To do that we will use the value for x from the first equation on the second one. We have:
2*y - 46 + y = 113
3*y = 113 + 46
3*y = 159
y = 159/3 = 53
x = 2*(53) - 46 = 60
The average sallary of a Master's is 60 thousand and of a Bachellor's is 53 thousand.
Answer:
So i just used the calculator to help me find the two co exisiting lines and then worked my way up to find the nearest decimal to fit the equation for the missing parablar length which was parallel to find the cointerior angle which lead me to get a decimal number involving an ordinary form number.
