What is the solution of log2x+7 27= 3

Step-by-step explanation:

We need to find the value of x

WE write the given log equation in exponential form'

can be written as

Using this we convert log to exponential form

27 can be written as 3^3

Both sides have exponent 3. To remove exponent 3 we take cube root on both sides.

Subtract 7 on both sides

Divide both sides by 2

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
