The base of an open rectangular box is of length (2x + 5) cm and width x cm. The area of this base is 58 cm
The height of the open box is (x - 2) cm.
a) Show that 2x + 5x -58 = 0
) Solve the equation 2x + 5x -58 = 0, giving your answers correct
to 2 decimal places
D) Hence calculate the volume of the box, stating the units of your answer.

a) x = 8.29 cm

D) V = 1125.27 cm³

Step-by-step explanation:

a) We can solve the equation as follows:

D) The volume of the box is given by:

Where:

l: is the length

w: is the width

h: is the height

The length of the rectangular box is:

The width is x = 8.29 cm.

And the height is:

Hence, the volume is:

I hope it helps you!        

the solution is h=10 because you add 9 to each side of the equation.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
