Answer:
x^2-16
Step-by-step explanation:
A= (b)(h)
A= (x+4)(x-4)
x^2-4^2
x^2-16
Answer:
Step-by-step explanation:
<u>Density</u>
The density of an object of mass m and volume V is given by
It can be expressed in common units like or any other combination of proper mass [M] by volume [V] units.
The data provided in the question is
Thus, the measured density is
We have expressed the result with 1 decimal place because the mass was measured to the nearest hundred milligrams (or one-tenth grams). Any further decimal is senseless because that precision comes from calculations, not from measurements.
Lacey, because you have to do the opposite when you want to get rid of a number. She subtracted 20 because it was originally positive 20. Chris messed up and did not do the opposite, subtraction, and instead he added 20
9.3 and were closest to another.
<u><em>Explanation</em></u>
First we will convert each given fractions into decimal form. So....
Then the scores are: 9.30, 9.50, 9.80, 9.95 and 9.25
So, 9.30 and 9.25 are closest to another as their difference is (9.30-9.25)=0.05
That means , 9.3 and were closest to another.
