A) ratio of the perimeters is the same as ratio of corresponding sides, so:
b) ratio of the areas is equal to k² so:
Answer:
inear equations Dear Dr Math: I hope you ... 10-(k+5) = 3(k+2) I would also appreciate any explanation. ... So we have to try to get all the "k's" on one side of the equation, and all the ... Let's look at the right side: 3(k+2) Okay, we could say this as 3 times the sum of k and 2.
Step-by-step explanation:
In all cases, if
has real coefficients, then any complex roots occur in conjugate pairs, so if
is a root, then so is
. Also, by the fundamental theorem of algebra, if
are roots to
, then for some constant
,

1. If
and
, then

Given that
, we have


2.

With
, we have


The rest are done in the same exact way.
