Answer:
Step-by-step explanation:
we are given the base area and the height of a solid figure
since the base area is not perfect square
we assure the solid figure to be a cuboid
remember that,
we are given l×w is 40 and h is 7
so substitute
simplify multiplication:
hence,
the volume of the figure is 280 in³
0
2x-6=2x+15
2x-2x=15+6
0x/0=21/0
x=0
