Answer:
perimeter = 71.4 m
Step-by-step explanation:
using the Pythagorean theorem:
CD² = 15.3² + (24 - 13.6)² = 234.09 + 108.16 = 342.25
CD = √342.25 = 18.5
perimeter = 24 + 15.3 + 13.6 + 18.5 = 71.4 m
Answer:
Step-by-step explanation:
Y = -x -1..........(1)
y = -2x + 7....(2)
Equating the two equations
-x -1 = -2x + 7
-x + 2x = 7+1
x = 8
Putting x in (1)
y = -8 - 1
y = -9
Answer:
volume = length×breadth×height
3×4×4=48in cube
