First answer is -5.
Second answer is -1.
Answer:

Step-by-step explanation:
we know that
In a rectangle, the two diagonals are congruent and each diagonal bisects the other
so
----> equation A
-----> equation B
step 1
Find the value of x
solve equation A

substitute the given values

solve for x

step 2
Find the value of KE

substitute the value of x

Remember that
-----> by each diagonal bisects the other
therefore

The answer should be 2 but i really don't know so its 2

<span>f(x)=âš(4x+6)
g(x)=âš(4x-6)
This is what we are given to work with, originally. Now, for the next part, we are asked to add the functions f(x) and g(x) together - and this is just what you do! You add the functions together, and then combine like terms.
(f+g)(x)=âš(4x+6)+âš(4x-6) --> âš(8x) + 6 - 6 :: and the 6's cancel each other, while the root 4x's add... and you have...
(f+g)(x)=âš(8x)
Thank you very much.</span>
Answer:
5 + 25 + 75 = 105 dollars
Step-by-step explanation:
The easiest way is to just take this day by day.
day 1: 5 dollars
day 2: day1^2 = 5^2 = 25
day 3: 3 * day2 = 3 * 25 = 75
Then sum them: 5 + 25 + 75
