Step-by-step explanation:
(i)
to find h(g(x)) , substitute x = g(x) into h(x) , that is
h(g(x))
= h(2x - 3)
= 4(2x - 3)
= 8x - 12
(ii)
given
h(g(x)) = g(x) , then
8x - 12 = (2x - 3) ← multiply both sides by 2 to clear the fraction
16x - 24 = 2x - 3 ( subtract 2x from both sides )
14x - 24 = - 3 ( add 24 to both sides )
14x = 21 ( divide both sides by 14 )
x = =
= 1.5
Step-by-step explanation:
Area of rectangle= l×b
= 4cm×6cm
= 24cm²
Area of circle. = πr²
radius of circle = diameter÷2=6÷2=3cm
Area of circle. = 3.14×3²=3.14×9
Area of circle. = 28.26cm²
Area of........... = 28.26cm²+24cm²
= 52.26cm²
