X = 3
AC = 8
explanation:
to find the value of x:
set AB + BC = AC
2x + x - 1 = 5x - 7
x = 3
to find the value of AC:
plug in x (3) into the AC expression
5(3) - 7 = ?
AC = 8
Answer:
Heat from the mantle forms convection currents causing the tectonic plates to diverge and form ocean basins.
Explanation:
Ocean basins form as a result of convection in the mantle along divergent margins.
- At a divergent margin, new crusts are being formed.
- It is said to be a constructive margin because new materials reaches through to the earth surface from there.
- The mantle convection pushes materials up and down away from heating centers and to cold regions and back and forth.
- This leads to the creation of cells which moves the overlying plate.
- The mantle materials are then able to reach the surface to form new ocean basin.
A descending order polynomial is one that lists the power in a descending order.
<h3>What is a Descending order polynomial?</h3>
In mathematics, this class of polynomial are most commonly used when the power of a term decreases for each succeeding term.
Therefore, the descending order polynomial is one that lists the power in a descending order.

Answer:
Maps and globes are drawn to scale and use symbols to represent topography and other features on Earth's surface. Grid lines on maps and globes are often used, with lines curving because the Earth is a sphere. The baselines for measuring distance on Earth are the equator and the Prime Meridian. Satellites are also often used as a mean to graph.
