Solve the equation for the given variable. Enter the value for the variable in the answer box 2 (n + 6) = 80

Step-by-step explanation:

Let's solve your equation step-by-step.

2(n+6)=80

Step 1: Simplify both sides of the equation.

2(n+6)=80

(2)(n)+(2)(6)=80(Distribute)

2n+12=80

Step 2: Subtract 12 from both sides.

2n+12−12=80−12

2n=68

Step 3: Divide both sides by 2.

2n

2

=

68

2

n = 34

Step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm
