Answer:
Simplifying
2(x + 3) + 3x + -10 = 0
Reorder the terms:
2(3 + x) + 3x + -10 = 0
(3 * 2 + x * 2) + 3x + -10 = 0
(6 + 2x) + 3x + -10 = 0
Reorder the terms:
6 + -10 + 2x + 3x = 0
Combine like terms: 6 + -10 = -4
-4 + 2x + 3x = 0
Combine like terms: 2x + 3x = 5x
-4 + 5x = 0
Solving
-4 + 5x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 5x = 0 + 4
Combine like terms: -4 + 4 = 0
0 + 5x = 0 + 4
5x = 0 + 4
Combine like terms: 0 + 4 = 4
5x = 4
Divide each side by '5'.
x = 0.8
Simplifying
x = 0.8

Answer:
The appropriate measure is cm/day.
Step-by-step explanation:
The best unit to measure the height of a plant = cm.
The best measure for time is day.
Rate refers to the ratio between units. Mostly, the difference in some unit when time passes.
She can measure the height of the plant in each day.
Hence, the appropriate unit for Dalla is cm per day.
