Step-by-step explanation:

oranges weigh 0.5 and grapefruits weigh 1.5

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
