(a)
x cubed is
=x^3=x3
5 times the cube of x is
=5x^3=5x3
4 times x is
=4x=4x
the quotient of 4 times x and 3 is
=\frac{4x}{3}=34x
so,
the difference of 5 times the cube of x cubed and the quotient of 4 times x and 3 is
=5x^3-\frac{4x}{3}=5x3−34x Answer
(b)
5 times cube of x is
=5x^3=5x3
5 times cube of x divided by 4 times x is
=\frac{5x^3}{4x}=4x5x3 Answer
(c)
difference of 5 times x cube and 4 is
=5x^3 -4=5x3−4
so,
the quotient of the difference of 5 times x cube and 4 and x is
=\frac{5x^3-4}{x}=x5x3−4 Answer
(d)
difference of 5 times x and 4 is
=5x-4=5x−4
so,
the cube of the difference of 5 times x and 4 is is
=(5x-4)^3=(5x−4)3 Answer

The area of the shaded region is
The area of the whole triangle - the area of the smaller triangle
So first let's find the area of the whole triangle.
a = 0.5bh
a = 0.5·5·12
a = 2.5·12
a = 30
Now find the area of the smaller triangle.
a = 0.5bh
a = 0.5·3·4
a = 1.5·4
a = 6
30 - 6 = 24
The answer is 24mm
Hope this helps! :)
