A triangle has side lengths of (2b+c)(2b+c) centimeters, (7b+4d)(7b+4d) centimeters, and (6d+2c)(6d+2c) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

(9b + 3c + 10d)cm

Step-by-step explanation:

Given the sides of a triangle expressed as (2b+c), (7b + 4d) and (6d+2c). The perimeter of the triangle is the sum of all the sides of the triangles.

Perimeter of the triangle = 2b+c + 7b+4d + 6d+2c

Perimeter of the triangle = 2b + 7b + c + 2c + 4d + 6d

Perimeter of the triangle = 9b + 3c + 10d

Hence the perimeter of the triangle is (9b + 3c + 10d)cm

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

no this is a nonlinear negative
