Explain the difference between solving the equation

will give answer x=4

will give answer x=4 and x= -4

Step-by-step explanation:

To understand the concept of why this happens, let us try to analyse both the equations.

1.

This equation actually tells that it has already been solved and we just need to tell the answer i.e. x=4. We can see the same by substituting values into x.

if x=4

which is a true condition.

if x=-4

which is a false condition.

2.

This equation actually tells that it needs solving and we need to find the answer. If we substitute values into x in the equation we have:

if x=4

which is true.

if x=-4

which is also true.

Hence we can see that :

can give two solutions i.e x=4 and x=-4 and

will give answer x=4

8y^50

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
