How many terms are in the binomial expansion of (3x + 5)9? 8 9 10 11

10

Step-by-step explanation:

we need to find out the number of terms in the binomial expansion

To find the number of terms we look at the exponent in the binomial expansion.

The exponent in binomial expansion is 9

number of terms in binomial expansion is n+1 terms

n is 9

So number of terms is 9+1=10

Number of terms in is 10

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.
