In a certain hexagon, the two shortest sides have the same length. The length of each remaining side is 2 inches more than the l

Nonamiya [84]

Answer:

length of the shortest side = 5 inches

length of the longest side is 7 inches

Step-by-step explanation:

Hexagon has 6 sides

Let x be the shortest side

length of the longest side is x+2

there are 2 shortest sides and 4 longest sides

To find perimeter we add all the sides

$Perimeter = 2(x) + 4(x+2)$

$38= 2(x) + 4x+8$

$38=6x+8$

Subtract 8 from both sides

$30=6x$

divide both sides by 6

x=5

length of the shortest side = 5 inches

length of the longest side is 7 inches

Can someone help me find the solution to these equations by using substitution

Vanyuwa [196]

1) (x,y) = no solution

2) x=-2y

-2y-y = 9

-3y = 9

y = -3

x = -2(-3)

x = 6

(x,y) = (6,-3)
