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.

step-by-step explanation:

f

i think it would be c

mark brainliest if im right

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
