Answer:
85
Step-by-step explanation:
The 9 th square number is 9² = 81
The 2 nd square number is 2² = 4
sum = 81 + 4 = 85
Step-by-step explanation:

Hence, coordinates A(2, 1), B(7, 1), C(2, 4) form a triangle.
Answer: 117
Step-by-step explanation:
Formula for arithmetic sequence is:
= a + (n - 1)d
22nd term = a + (n - 1)d
= a + (22 - 1)d = a + 21d
where, a = 12
d = 17 - 12 = 5.
Therefore, 22nd term will be:
= a + 21d
= 12 + 21(5)
= 12 + 105
= 117
The 22nd term is 117
7+18/(6-3)
7+18/3
25/3=8.333
So bassically
his commision rate is
x% times 190000=comission
so x% times 190000=11400
divide both sdies by 190000
x%=11400/190000
solve for x percent
11400/190000=114/1900=3/50
x%=3/50
percent means parts out of 100 so x%=x/100
x/100=3/50
3/50=6/100
x/100=6/100
multiply both sdies by 100
x=6
the commision rate is 6%
