Answer:
96
Step-by-step explanation:
We have to find number of 9 digit palindromes when all digits are even and each digit appearing not more than twice.
Digits used here
0,1,2,3,4,5,6,7,8,9
Total number of even digits=0,2,4,6,8=5
Now,
0 cannot be used for first place if number is 9-digit number.
Firs place can be filled by number of ways=4
Second place can be filled by number of ways=4
Third place can be filled by number of ways=3
Fourth place can be filled by number of ways=2
Fifth place can be filled by number of ways=1
Total number of ways=
Total number of ways=96
Hence, total number of 9-digits palindromes when all digits are even and appearing not more than twice=96
Factor first: (sinx+1)(2sinx-1)=0
sinx+1=0 or 2sinx-1=0
sinx=-1 or sinx=1/2
0≤x≤360, so x=270, or x=30 or x=150
For this case we must represent the following expression algebraically, in addition to indicating its result:
"2 plus 9"
So, we have:
By law of the signs of the sum, we have that equal signs are added and the same sign is placed:

-312
2.
a. Solution:
5y-3+3=-18+3
5y=-15
y=-15/5
y=3
b. Solution:
-3x-9+9=0+9
-3x=9
x=9/-3
x=-3
c. Solution:
4+3-3(z-8-3)=-23-3
4(z-5)=-20
4z-20=-20
4z-20+20=-20+20
4z
z=4
d. Solution:
1-2+2(y-4+2)=5+2
3(y-2)=7
3y-6=7
3y-6+6=7+6
3y=13
y=13/3
y=4.33
