Answer:
The length is 91 meters
Step-by-step explanation:
The perimeter formula is 2W · 2L = 314
We know the width is 66 m, so we can then say:
132 · 2L = 314
-132 -132
2L = 182
L = 91

3.2 -9x+ 7.1 -3x
= (-9x -3x)+ (3.2+ 7.1) (combine like terms)
= -12x+ 10.3
The final answer is -12x+ 10.3~
Answer:
x > -2
Step-by-step explanation:
3(1 – x) < 9
Divide each side by 3
3/3(1 – x) < 9/3
1-x < 3
Subtract 1 from each side
1-x-1 < 3-1
-x < 2
Multiply each side by 1, remembering to flip the inequality
-x*-1 > 2*-1
x > -2
Open circle at -2, line going to the right
