Step-by-step explanation:
xy/z where x = 3 y = -4 and z = -6
Step 1. Substitute x for 3 y for -4 and z for -6
(3)(-4)/(-6)
Step 2. Multiply
-12/-6
Step 3. Remove the negative signs (only when the numerator and the denominator are both negative numbers)
12/6
Step 4. Simplify

f = 22
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
140° is an exterior angle of the triangle, thus
4f + 1 + 51 = 140, that is
4f + 52 = 140 ( subtract 52 from both sides )
4f = 88 ( divide both sides by 4 )
f = 22
