Answer:
Step-by-step explanation:
To find this equation in standard form, first, write it in factored form. This looks like . Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.
- Following the FOIL method, you should multiply the first terms in each binomial,
, which equals
.
- Then, the outside terms,
. This equals
.
- Next, the inside terms,
.
- Finally, the last terms,
, this equals
.
Then, add all of the terms together . To get the standard form, combine like terms, this comes out to
.
Answer:
Polygon q’s area is one fourth of polygon p’s area
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> polygon q’s area
y-----> polygon p’s area
so
In this problem we have
substitute
therefore
Polygon q’s area is one fourth of polygon p’s area
