What is the minimum value of 2x + 2y in the feasible region?

Liono4ka [1.6K]

The perimeter of this kite is 108 cm.

taurus [48]

Answer:

n is equal to 26

Step-by-step explanation:

Equation: n+ n + (n+2) +(n+2) = 108

so: 2n + 2(n+2) = 108

2n + 2n + 4 = 108

4n + 4 = 108

4n = 108 - 4

4n = 104

n = 104/4

n = 26

Solve for n in the literal equation a(n-2)+5=bn

Helga [31]

Answer:

Answer is below

Step-by-step explanation:

a(n-2)+5=bn

Add -bn to both sides

an-2a+5+(-bn)=bn+(-bn)

an-bn-2a+5=0

add two a to both sides

an−bn−2a+5+(2a)=0+(2a)

an−bn+5=2a

Add -5 to both sides

an−bn+5+(-5)=2a+(-5)

an−bn=2a−5

Factor out our variable

n(a−b)=2a−5

Divide both sides by a-b

n(a-b)/a-b=2a-5/a-b

n=2a-5/a-b

Hope this helps
