<span>To be both complex and imaginary, the answer would have to include "i" as well as have the form "a + bi". The first example, 3i - 5, fits. This would look to be the only example that does fit. The negative square root of 14 would be imaginary, but not complex.</span>
Angle A is 2x + 3
Angle B is 4x + 2
Angle C is 2x - 1
The three angles add up to 180
So:
2x + 3 + 4x + 2 + 2x - 1 = 180
Combine terms
8x + 4 = 180
Subtract 4
8x = 176
x = 22
Now we solve for the angles:
Angle A is 2(22) + 3 = 44 + 3 = 47
Angle B is 4(22) + 2 = 88 + 2 = 90
Angle C is 2(22) - 1 = 44 - 1 = 43
Quick check: 47 + 90 + 43 = 180
First, convert the weight of the child from pounds to kilograms using the conversion factor given. The operation gives an answer of 19.3431 kg. With this weight and the given average dosage, the child should be prescribed with 174.0879 mg oxcarbazepine. From the concentration given, the final answer is 2.90 mL.
5(x+40-7) < 23
5x +33 < 23
5x < 23 -33
5x < -10
x < 2
Hope it helps I couldn’t do the line under the less than sign but I hope it helps!
=-2 here you go hope it helps
