Answer:
Step-by-step explanation:
We have the following quadratic equation
The factored expression will have the following form
Where b and c are two real numbers which when added together result in -1, and multiplying them results in -20
You can verify that the numbers that meet this condition are:
-5 and 4
Then the factors are:
Answer: just line up the decimals.

is there a specific question I can help you with?
Answer:
72 inches
Step-by-step explanation:
Lets say d is the depth of the water in the soil, and s is the cumulative snowfall.
d = s / 12
If d = 6:
6 = s / 12
s = 72
A cumulative snowfall of 72 inches will melt into 6 inches of accumulated water in the spring soil.
Dear, questioner What to explain?
3.5 × 10 = 35.0
The mistake is that you only added a zero to the answer (3.5 -> 3.50), but you forgot to replace the point in your answer (because 3.50 is wrong and 35.0 is correct). Hence, you should have replaced to point, by moving it one spot to the right.
