If the Perimeter of the triangle 15 centimeters, what is the value of n

Step-by-step explanation:

n+2n+1+5n-6=15

= 8n + 1 - 6= 15

= 8n + 1 - 6 + 6 = 15 + 6

= 8n +1 = 21

= 8n + 1 - 1 = 21 - 1

=8n = 20

= 8n / 8 = 20 / 8

= n = 2.5

the value of ‘n’ is 2.5

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

8.3 and the 3 is repeating

hope this .
