The diagram shows a shape made out of solid wood. The shape is made by cutting a square hole all the way through a wooden cube. The cube has edges of length x cm.
The hole has a square cross section of side 3cm.
The volume of the wood in the shape is 70cm^3.

Show that x^3 - 9x = A
Where A is a constant to be found.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

the answers are in the images, i received 100% on this assignment. hope this !

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
