Answer:

g= -5

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

84-(4*(1-4*g))=0

84 - 4 • (1 - 4g) = 0

3.1 Pull out like factors :

16g + 80 = 16 • (g + 5)

16 • (g + 5) = 0

4.1 Solve : 16 = 0

This equation has no solution.

A a non-zero constant never equals zero.

4.2 Solve : g+5 = 0

Subtract 5 from both sides of the equation :

g = -5

Step-by-step explanation:

Step 1: Define equation

84 = 4(1 - 4g)

Step 2: Solve for g

Distribute 4: 84 = 4 - 16g
Isolate g term: 80 = -16g
Isolate g: -5 = g
Rewrite: g = -5

Step 3: Check

Plug in g into the original equation to verify it's a solution.

Substitute in g: 84 = 4(1 - 4(-5))
Multiply: 84 = 4(1 + 20)
Add: 84 = 4(21)
Multiply: 84 = 84

Here we see that 84 does indeed equal 84.

∴ g = -5 is a solution of the equation.

Two parallel lines are _____ coplanar.

Answer:

1. always

2. sometimes

Step-by-step explanation:

Two lines are coplanar if they lie in the same plane or in parallel planes. There is ALWAYS a plane which contains two parallel lines (see first attached image for details).

Two lines that lie in parallel planes are sometimes parallel. For example, see at second image. Planes $\alpha$ and $\beta$ are parallel. Consider pair of lines $a$ and $a_1$ - they are parallel, but if you consider the pair of lines $a$ and $b_1$ , you can see they are not parallel.
