How to solve -c(11c + 4)
saul85 [17]

Answer:

-11c^{2} - 4c

Step-by-step explanation:

You have to distribute the -c to both of the numbers in the parentheses, so the eleven would become negative, and c multiplied by c is c squared. The positive 4 becomes negative 4, and 4 times c is 4c. Hope that helps!

Eduardwww [97]

Answer:

n = -4

Step-by-step explanation:

You must write and solve a symbolic equation.

n - 6 = 5(n + 2), or

n - 6 = 5n + 10

Combining like terms, we get:

-16 = 4n,

and so n = -4
