Multiply using distributive property.

(2m-5)(3m+8)

PLEASE HELP

6m^2 +m -40

Step-by-step explanation: Distributing binomials calls for the FOIL method.

Multiply the First times the First: 3m×2m= 6m^2. (^2 means squared when we can't use superscript for exponents.)

Then multiply and combine the Outside and Inside terms: 2m ×8=16m. and -5 ×3m= -15m

16m - 15m = m

Then multiply the Last terms: -5×8= -40

You end up with

6m^2 + m -40

6m^2 + m - 40.

Step-by-step explanation:

(2m - 5)(3m + 8)

= (2m * 3m) + (-5 * 3m) + (2m * 8) + (-5 * 8)

= 6m^2 - 15m + 16m - 40

= 6m^2 + m - 40.

Hope this helps!

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.
