(60 / - 20 ) x 100% = 300%
6 x 4=24 so the area of the donut 24 which is the answer to the question
Answer: 1.2
Step-by-step explanation:
To get 8% you have to do 8/100
that equals .08
Multiply .08 with 15 and it equals 1.2
The answer to (-5)-3 is -8. I may be wrong but I did the work.
4x² + 3x + 5 = 0
x = <u>-3 +/- √(3² - 4(4)(5))</u>
2(4)
x = <u>-3 +/- √(9 - 80)</u>
8
x = <u>-3 +/- √(-71)
</u> 8<u>
</u>x = <u>-3 +/- √(71 × (-1))</u>
8
x = <u>-3 +/- √(71) × √(-1)
</u> 8<u>
</u>x = <u>-3 +/- 8.43i
</u> 8
x = -0.375 +/- 1.05375i
x = -0.375 + 1.05375i x = -0.375 - 1.05375i
