Answer:
The first error consists in the multiplication of f (x) = 100 * (1.25), the value she mentions is incorrect since it is 125.
It would be a 125% increase really.
In order for LaTanya's phrase to have no error she had to mention that it was a 25% increase over the original amount, in this way, the phrase would make sense and be valid.

Answer:
missing side length is 12
Step-by-step explanation:
similar means that all correlating pairs of sides have the same ratio (old side length) / (new side length).
so, when we know the ratio of one pair, we can apply it to any other side to calculate the correlating side.
we see, when we go from small to large, that we have the ratio 32/40 = 4/5.
so, multiplying the larger side by this, we get the shorter side.
15 × 4/5 = 3 × 4 = 12
the proportion part in your picture is a bit confusing :
yes,
x/15 = 32/40 = 32/40
I don't know, why this last expression was repeated.
x/15 = 32/40
x = 15×32/40 = 15×4/5 = 3×4 = 12
as you see we get of course the same result doing it that way.
Answer:
.
Step-by-step explanation:
Single numbers, variables and product of number and variables are know as terms. In an algebraic expression each term is separated by an addition "+" sign.
The given expression is
It can be written as
Therefore, the terms are .
