Answer:
3rd option
Step-by-step explanation:
the denominator cannot be zero as this would make the expression undefined.
equating the denominator to zero and solving gives the values that x cannot be.
x² - 7x - 18 = 0 ← in standard form
(x - 9)(x + 2) = 0 ← in factored form
equate each factor to zero and solve for x
x - 9 = 0 ⇒ x = 9
x + 2 = 0 ⇒ x = - 2
then
x = - 2, x = 9 ← are the excluded values
1.
the angle should add up to 360
so
360-110-90=160
that is the answer
2.
the angle has to add up to 90
so
90-57=33
It will take 9 minutes and 20 seconds.
There's 120 seconds in 2 minutes and divide it by 3 seconds you'll get 40 seconds for each photographs. 40*2=80
