In ΔUVW, w = 840 cm, u = 350 cm and ∠V=63°. Find the area of ΔUVW, to the nearest square centimeter.

Me because some of question i don’t understand

Which expression is equivalent to 8(k + m) − 15(2k + 5m)?

Acompany manufactures large valves, packed in boxes. a shipment consists of 1500 valves packed in 75 boxes. each box has the outer dimensions 1.2 x 0.8 x 1.6 m and the inner dimensions 1.19 x 0.79 x 1.59 m. the boxes are loaded on a vehicle (truck + trailer). the available capacity in the vehicle combination is 140 m3. each valve has a volume of 0.06 m3. - calculate the load factor on the box level (%). - calculate the load factor on the vehicle level (%). - calculate the overall load factor (%).
