Describe the error in the work shown. A small submarine starts at –1,260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes. What is the new position of the submarine in relation to sea level?

It Has To be right

–1,260 + (–5)(12)= –1,260 + 60

= –1,200

The error is that instead of subtracting 60 feet from -1260, the expression adds this quantity.

Step-by-step explanation:

If starting at -1260 feet, and then going down (descending) 60 feet (result of descending 5 feet every minute for 12 minutes), the correct operation is:

-1260 + (-5)(12)= -1260-60= -1320

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
