First calculate his gross salary after his 401k contributions:

Then find the amount of taxes withheld:

5,760 dollars went towards taxes.
The simplified expression is: -14s⁴-2s²+3s-3.
First group all the like terms together.
(-8s⁴)+(-6s⁴)=-14s
-2s
7s+(-4s)=3s
-3
Then put the expression back together, starting with the term that has the largest exponent, then working your way down. You would then get: -14s⁴-2s²+3s-3.
Answer:
67
Step-by-step explanation:
Since the diagonals in a rectangle are congruent, AC=BD and
7x+18=10x-3
We need to separate x -- to do that, we can first subtract 7x from both sides, resulting in
18=3x-3
Next, add 3 to both sides to get
21=3x
Divide both sides by 3 to get
x=7
Then, we just plug x into 10x-3 to get BD = 7*10-3 = 67
