Answer:
a=5, b=-2
Step-by-step explanation:
If you simplify the equation, you get:
3ax +6 -4x -4b - 11x - 14 = 0 =>
3ax - 15x -4b -8 = 0
group together x's and constants:
(3a-15)x -8 -4b = 0
To make this 0 for all x, we have to find an a such that 3a-15 = 0 and b such that -8-4b = 0. this leads to a=5, b=-2
Answer:
in scientific notation = 2.58 × 10⁵

Answer:
402
Step-by-step explanation:

Answer: D) Flat area with a large number of plants
The roots of the plants hold in the soil, which prevents/reduces erosion.
The steeper slope means gravity pulls down the soil material faster, since there is less ground in the way to hold it up, so to speak. So flatter areas are less prone to erosion compared to steeper areas.
So that's why overall, flatter areas with lots of plants would have the least erosion.
