He forgot to factor the 2 out of -8x
8m - 5n + 2m + 6n =Simplifying
8m + -5n + 2m + 6n = 0
Reorder the terms:
8m + 2m + -5n + 6n = 0
Combine like terms: 8m + 2m = 10m
10m + -5n + 6n = 0
Combine like terms: -5n + 6n = 1n
10m + 1n = 0
Solving
10m + 1n = 0
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-1n' to each side of the equation.
10m + 1n + -1n = 0 + -1n
Combine like terms: 1n + -1n = 0
10m + 0 = 0 + -1n
10m = 0 + -1n
Remove the zero:
10m = -1n
Divide each side by '10'.
m = -0.1n
Simplifying
m = -0.1n.
After
using a calculator to find sin 21 degrees and rounding it to four decimal places,
I got 0.3584. The correct answer between all the
choices given is the first choice. I am hoping that this answer has satisfied
your query and it will be able to help you in your endeavor, and if you would
like, feel free to ask another question.
Y = 0.5x + 16.5
parallel so y = 0.5x + c
12 = 0.5 * -9 + c
12 = -4.5 + c
c = 16.5
y = 0.5x + 16.5

Answer: D
Step-by-step explanation:
An equation would look like this:
x+1=3
An expression would look like this:
x+1
As you can see, an expression has no equal sign. Conversely, an equation does. That is the primary difference between a(n) (algebraic) expression and equation.
