What is the value of x2+9x+20 when x could be -5, -3 or -6

Mathematics

ANTONII [103]3 years ago
3 0

Answer:

Step-by-step explanation:

You should use a ^ to indicate an exponent. x^2 is the same as x².

x² + 9x + 20

Replace the x with (-5).

(-5)² + 9(-5) + 20 = 25-45+20 = 0

Then do the same with x = (-3):

(-3)² + 9(-3) + 20 = 9 - 27 + 20 = 2

You can do x = (-6)

I payed for a subsciption my bank has already been debted but it wont let me use it. why not?
ANEK [815]

Answer:

If your payment didn’t go through, change your preferred payment method/add another payment method.

For example, if your preferred payment method is your bank account, we'll always try to use your bank account first for payments. If there's an issue with your bank account, you can change your preferred payment method to a different one, such as a debit or credit card. If you only have a card registered on your account, try adding and confirming a bank account.
