Answer:
Step-by-step explanation:
<u>Direct variation equation:</u>
- y = kx, where k is constant of variation
<u>Given:</u>
<u>The equation is:</u>
<u>Find the value of x when y = 168:</u>
- 168 = 12x
- x = 168/12
- x = 14
Some examples of geometric constraints include parallelism, perpendicularity, concentricity and symmetry. Parallelism occurs when two or more lines or axes of curves are equidistant from each other. Perpendicularity is a constraint in which lines or axes of curves intersect at right angles.
let's recall that i⁴ = 1 so then 
Answer:
6cm
Step-by-step explanation:
Volume of cuboid = length × breadth × height
Length = x
Breadth = 4cm
Height = 5cm
Volume = 120cm³
Volume = 4 × 5 × x
120 = 20x
Divide both sides by 20
20x/20 = 120/20
x = 6cm
