Answer:

Step-by-step explanation:
has the following properties:

º = 1.75 π (π = 180º)
therefore, z₁ = 13 * [ cos(1.75 π) + i sin(1.75 π) ] = 13*[cos(1.75π - 2π) + i sin(1.75π - 2π)] = 13*[cos(-π/4) + i sin(-π/4)] {this is due to periodicity} = 13*(√2/2 - i √2/2) = 
☆Open the brackets by multiplying out
120 - 84 + 9g = 2g + 5g + 36
☆Collect like terms
9g - 2g - 5g = 36 -120 +84
2g = 0
☆Divide by 2 to find x
g = 0

Answer: The answer is D. 240 grams
Step-by-step explanation:
1. Find the volume.
2cm×3cm×5cm=30 cubic centimeters
2. Find the volume of the other box.
4cm×9cm×5cm=180 cubic centimeters.
3. Divide. 180÷30=6
4. 6 times the amount it can hold, 40=240 grams of clay.
Hope that helped!
