Question

d) 8(x-4) + 2 = 42 solve the equation​

Answer 1

Answer:

According to the Triangle Law of vector addition, a minimum of three vectors are needed to get zero resultant. So we can say that a minimum of 3 coplanar vectors is required to represent the same physical quantity having different magnitudes that can be added to give zero resultant.

Answer 2

$\huge{ \boxed{ \bf{ \green{Solution }}}}$

$\bold{8( x - 4) + 2 = 42}$

$\bold{8x - 32 + 2 = 42}$

$\bold{8x = 42 + 32 - 2}$

$\bold{8x = 72}$

$\bold{x = \frac{72}{8} }$

$\bold{ \therefore{x = 9}}$
