Answer:
Option B - 11.6 m below the surface of water.
Step-by-step explanation:
Given : Ben and Cam are scuba diving. Ben is 15.815.8=15.8 meters below the surface of the water. Cam is 4.24.2= 4.2 meters above Ben.
To find : What is Cam's position relative to the surface of the water?
Solution :
Ben is 15.8 meters below the surface of the water.
Cam is 4.2 meters above Ben.
So, Cam is below the surface of water by 
meter.
Therefore, Option B is correct that Cam is 11.6 meters below the surface of the water.
Answer:
i dont
Step-by-step explanation:
know i answerd because i need points
x = 4
x = -1
x = 0
Equation at the end of step 1 :
((3 • (x3)) - 32x2) - 12x = 0
Step 2 :
Equation at the end of step 2 :
(3x3 - 32x2) - 12x = 0
Step 3 :
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
3x3 - 9x2 - 12x = 3x • (x2 - 3x - 4)
Trying to factor by splitting the middle term
4.2 Factoring x2 - 3x - 4
The first term is, x2 its coefficient is 1 .
The middle term is, -3x its coefficient is -3 .
The last term, "the constant", is -4
Step-1 : Multiply the coefficient of the first term by the constant 1 • -4 = -4
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .
-4 + 1 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
x2 - 4x + 1x - 4
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-4)
Add up the last 2 terms, pulling out common factors :
1 • (x-4)
Step-5 : Add up the four terms of step 4 :
(x+1) • (x-4)
Which is the desired factorization
B maybe or A
Because 15 percent of 212 is 31.8 so it’s closer to 40 maybe
