Answer:
b could be -1 or 0
Step-by-step explanation:
f(x) = 3x^2 +bx+2
if it has no real roots, the discriminant must be less than zero
b^2 -4ac <0
a=3 b=b c=2
b^2 - 4(3)(2) <0
b^2 - 24 <0
b^2 < 24
Taking the square root of each side
b< 2 sqrt(6) and b > 2 sqrt(6)
b could be -1 or 0
Answer:
50.27cm^2
Step-by-step explanation:

Hello there I hope you are having a great day :)
<u>The Topic Shifting digits:</u>
Shifting digits - Putting a digit in a different place. For a example Take the number 358 you would exchange the number from the hundreds that would equal 838 this meaning that you what to make a bigger number than a small one.
Examples:
1. 358 equal 838
2. 204 equal 402
3. 188 equal 881
You are just making them smaller to a greater number :)
Hopefully that helps you :)
