Step-by-step explanation:
There are 492 <em>seconds</em><em>.</em>
Answer:
492 seconds.
Every minute is 60 seconds.
Over here, 8minutes,12seconds has a value of minute in it.
Since we're dealing with seconds, we convert the 8 minutes into seconds and add it to the 12 seconds to get the overall value.
If 1 minute=60seconds
8 minutes=x
x=60×8=480 seconds
=> 480+12= 492 seconds.

f(x)=4x² - 10+2
f(-7) = 4x² - 10 + 2
= 4(-7)² - 10 + 2
= 4 (49) - 10 + 2
= 196 - 10 + 2
= 188
