Hello,
52% of 230 = 52/100 × 230 = 0,52 × 230 = 119,6
23 is the constant rate of change..............
Answer:
an = a(n-1) - 7
Step-by-step explanation:
the second term is smaller than the first term 7.
a20 = a19 - 7
a19 = a18 - 7
=> a20 = (a18 - 7) - 7
Then you can accumalate until a1
-> a20 = a1 - 19*7 = 86 - 19*7 = -47
Answer:
or 
Step-by-step explanation:
To solve the quadratic equation we must factor the expression
Look for 2 numbers that when you multiply them, obtain the result -100 and when you add them, obtain the result -15.
You can verify that these numbers are -20 and 5

Then the polynomial factors are

The zero product property says that if two terms
then
or 
So
or 
or 
The answer is the first row 12, 24, 48, 96
