While scuba diving, Rajeev dove to a depth of 12.6 feet below the surface of the water and then descended another 8.7 feet. What expression can be used to find Rajeev’s new position? (This is test my first question :D) What is answer tell me NOW.

The expression that can be used it -12.6+-8.7=-21.3

Make sure you look at what I put because it is negative 12.6 AND negative 8.7 which is why there is an addition mark in between them both

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
