Iwill give brainliest to the first correct !

a group of researchers are exploring a part of the ocean floor. on their first dive, they explore a part of the ocean floor that is 60 feet below sea level. this depth can be represented by the integer -60. on their second dive, researchers explore a deeper depth.
what is the inequality that represents the possible depth (d) of the researches second dive?

60d

Step-by-step explanation: if they are going down from 60depth already and they are going more down without telling the how much they go down it tells you is multipucation but it doesnt show the number then the answer will be 60d

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
