Answer:
Let L = length
Let w = width
Perimeter = 2L + 2w
L = 100
Perimeter > 400
2(100) + 2w > 400
200 + 2w > 400 is the inequality
Subtract 200 on both sides of inequality.
2w > 200
w > 100
The width is at least 100 centimeters
cubic means 3 so there is a total o 3 roots
there is 1 real zero ( where the line crosses the x axis) the other 2 would be complex zeros
Answer is D

</span>44,596,251 = <span>45,000,000
</span>28,257,934 = <span>28,000,000
</span>45,000,000 - 28,000,000 = 17,000,000
answer
17,000,000
-1.25, multiply both by 5, -45 divided by 36 is -1.25
