Answer:

x = 19

Step-by-step explanation:

(5x + 4)° + (x - 2)° + (3x + 7)° = 180°

(5x + x + 3x)° + (4 - 2 + 7)° = 180°

9x° + 9° = 180° → ÷9

x + 1 = 20

x = 20 - 1

x = 19

lisabon 2012 [21]

Answer:

2x+2y ≤ 64

x=2y+2

Step-by-step explanation:

x = length

y = width

the length is 2 more than twice the width or 2 more than twice y

x = 2+2y

the perimeter of the garden = 2 times the length + 2 times the width

she have 64ft of wire so the perimeter should be equal or less than 64 ft

64 ≥ 2x + 2y
