Answers
Step-by-step explanation:
1)additive inverse is -5/3
2)x+7=19
x=19-7=12
3)all the angles of the rectangle sum up to form 360 degree as each angle measures 90 degree and a rectangle is a quadrilateral ,so the sum of all angles should be 360 degree
10)side of the cube=3 m
volume=(a×a×a)cube units=(3×3×3)cubic metre=27 cubic metre
8)a cuboid generally has six six faces 8 vertices and 12 edges
9)the unit digit number of cube of 1128 is 2
6)the area of a parallelogram can be taken out by multiplying it's breadth and height and as you have not given the units , sorry I can't help you in this question...
4)the exterior angle of a regular hexagon measures 6o degree
I have answered any 8 questions of the following which you have given hope it will help you!!!
