You are 124.6 meters above sea level. your partner is 39.8 meters below sea level. which expression shows the difference in your elevations? a. 124.6 - 39.8 b. -124.6 -39.8 c. -124.6 + 39.8 d. 124.6 - (-39.8)

d. 124.6 - (-39.8)

Note that you are above sea level (+124.6), while your partner is below sea level 939.8). To solve the difference, you must subtract the numbers.

D. is your answer, for it fits this description

hope this helps

for b its (t) and c its (d)

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
