Answer 1

Answer:

i)$15a - 10(a^{2} )$  ii) $7-0.6a/5$ iii)$(3p^{4} -4p^{3} +10p^{2} )/18$

Step-by-step explanation:

i)According to the distributive property,

5a(3 - 2a) = (5a * 3) - (5a * 2a) = $15a - 10(a^{2} )$

ii)According to the distributive property,

(-3a/5)(-7/3a + 0.2) = [(-3a/5)(-7/3a)] + [(-3a/5)(0.2)]  

= (7/5) + (-0.6a/5) = $7-0.6a/5$

iii)According to the distributive property,

$p/3((p^{3}/2) - (2p^{2} /3) + (5p/3))$ = $[p/3 * (p^{3} /2)] - [p/3 * (2p^{2} /3)] + [p/3 * (5p /3)]$

= $(p^{4} /6) - (2p^{3} /9) + (5p^{2} /9)$ = $(3p^{4} /18) - (4p^{3} /18) + (10p^{2} /18)$ = $(3p^{4} -4p^{3} +10p^{2} )/18$
