Answer:
Actual height of church = 512 feet
Step-by-step explanation:
Given:
Scale model;
1 inch = 256 feet
Height of church (Scale model) = 2 inches
Find:
Actual height of church
Computation:
Actual height of church = Height of church (Scale model) x scale length
Actual height of church = 2 inches x 256 feet/inches
Actual height of church = 2 x 256 feet
Actual height of church = 512 feet
In order to answer the question we need the lengths to do the math.
We want to simplify:
first we factorize
as
then multiply
by
to equalize the denominators of the first expression, and add the fractions.
simplify x+3:
a.
b.
steps already described
c.
x cannot be -1, nor -3 because the fractions with denominators (x+1) and (x+3) would not be defined.
