You can just pick any 5 digit decimal and multiply it with any 4 digit decimal to check.
You will see that it has 9 digits after the decimal.

Answer:
n=3
Step-by-step explanation:
-4n-40=-2(7n+5)
Distribute the -2
-4n -40 = -14n -10
Add 14n to each side
-4n+14n -40 = -14n +14n-10
10n -40 = -10
Add 40 to each side
10n -40+40 = -10+40
10n = 30
Divide each side by 10
10n/10=30/10
n =3
The answer is no, as the y value is negative while the x value is positive
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.
