Elsa tries to solve the following equation, and
determines there is no solution. Is she correct?
Explain.
log2x = log2(3x + 5) + 4

Yes, Elsa is correct.

Step-by-step explanation:

The given equation is

Elsa tries to solve the equation, and determines there is no solution. We need to check whether she is correct or not.

The given equation can be rewritten as

On comparing both sides, we get

The value of x can not be negative because log is not defined for negative values.

Therefore, Elsa is correct and given equation have no solution.

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
