17)
x² + 8 = -8
x² = -8 - 8
x² = 16
x = ±√-16
x = ±√16i
x = <span>±4i
</span>
18)
x² + 5 = -3
x² = -3 - 5
x² = -8
x = ±√-8
x = ±√8i
x = ±2√2i
19)
x² + 3 = 0
x² = -3
x = ±√-3
x = <span>±</span>√3i
hope this helps, God bless!
Answer: see attachment
<u>Step-by-step explanation:</u>
Since A = C = 105° and D = 60°,
then A + B + C + D = 360°
105° + B + 105° + 60° = 260°
B + 270° = 360°
B = 90°
It will cost her 1,710 dollars because 10 times 17 is 170 and 170 times 16 is $1,710
