Answer:
a). 8(x + a)
b). 8(h + 2x)
Step-by-step explanation:
a). Given function is, f(x) = 8x²
For x = a,
f(a) = 8a²
Now substitute these values in the expression,
=
=
=
= 8(x + a)
b). =
=
=
= (8h + 16x)
= 8(h + 2x)
t = 2 → A true
given I = PRT
to find T , divide both sides by PR
note that R = 6% = = 0.06
T = = 42/( 350 × 0.06 ) = 2
