Answer:
A
Step-by-step explanation:
A is not a polynomial as the power of x is less than one
Z=-3 is the correct answer. Use math papa if you need help with the steps on how we got z=-3

Answer: </h3><h3>
There are 75 coins that aren't nickels. </h3><h3>
One equation you could use is 75+n = 92</h3>
(This solves to n = 17 meaning there are 17 nickels)
=====================================================
Explanation:
"There are 25 pennies, 21 dimes, and 29 quarters", so there are 25+21+29 = 75 coins so far. This is the amount of coins that aren't nickels. The rest are nickels, which is some amount n. This adds to the 75 to get 75+n. Set this equal to 92 because there are 92 coins in all. That's how we end up with 75+n = 92.
-----
Extra info
The equation 75+n = 92 is the same as n+75 = 92. Subtract 75 from both sides to isolate n. You should get n = 17 after doing so.
Answer:
1. x = 21
2. x = 19
Step-by-step explanation:
Since the interior angles of all quadrilaterals add up to 360, all we have to do is add them up and set them equal to 360. Combine like terms and we get
7x + 213 = 360
Which further turns to 7x = 147
So x = 21
For the second problem, it's the same thing
By the end we get 2x + 8 = 46
2x = 38
x = 19
Hope this helps
Hello,
(√11-√3)(√11+√3)(√11-√5)=(11-3)(√11-√5))=8(√11-√5)
