Elevation is a measure of height in relation to sea level. The highest feature on Earth is Mount Everest with an elevation +29,0

Sphinxa [80]

Answer:

$Sea\ Level = 0\ ft$

The farthest point is the Challenger Deep

Step-by-step explanation:

Given

$Highest = +29029ft$

$Least = -35,797ft$

Solving (a): The sea level

Both elevations had signs in front of them.

The sea level is the point at the neutral level, neither positive nor negative.

Hence:

$Sea\ Level = 0\ ft$

Solving (b): Farthest Point.

The farthest point is the one with the highest magnitude.

Comparing

$Highest = +29029ft$ to $Least = -35,797ft$

-35,797 ft has the highest magnitude.

Hence:

<em>The farthest point is the Challenger Deep</em>

(4x²y3 + 2xy2 - 2y) - (-7x²y3 + Oxy2 - 2y)

faust18 [17]

Answer:

=11x2y3-oxy2+2xy2

Step-by-step explanation:

Simplify:

4x2y3+2xy2-2y-((-7x2)(y3)+oxy2-2y)

Distribute negative sign(-)

=4x2y3+2xy2+-2y+7x2y3+-oxy2+2y

Combine like terms

=(4x2y3+7x2y3)+(-oxy2)+(2xy2)+(-2y+2y)

=11x2y3-oxy2+2xy2
