b and c

Step-by-step explanation:

Have a look at lines b and c. Note that the two slopes (-1/2 and +2) are negative reciprocals of one another. This is a sure sign that lines b and c are perpendicular.

Mathematics

Explanation is below

Step-by-step explanation:

Here ya go

Simplify both sides of the equation.

$\frac{1}{4} v+2=8$

Subtract 2

$\frac{1}{4} v+2-2=8-2\\\frac{1}{4} v=6\\$

Multiply both sides by 4

$4(\frac{1}{4} v)=(4)(6)\\v=24\\$
