What is the simplified expression for 3a^2+9ab+5-4a^2-4ab +3?

seraphim [82]

Answer:

$-4a^2+4ab+8$

Step-by-step explanation:

our expression is

$3a^2+9ab+5-4a^2-4ab+3$

we are asked to simplify the expression

in order to that we first bring the like terms together

like terms are those having the same variable or same combination of variables with exactly same degrees

Hence it would be like

$3a^2-4a^2+9ab-4ab+5+3$

now we simplify the like terms

$3a^2-4a^2=-4a^2$

$9ab-4ab=4ab$

$5+3=8$

Hence

$3a^2-4a^2+9ab-4ab+5+3=-4a^2+4ab+8$

A bag contains tiles with the letters p -r-o-b-a-b-i-l-i-t-y Tyler chooses a tile without looking and doesn't replace it he choo

ipn [44]

Answer:

$\frac{1}{55}$

Step-by-step explanation:

Total number of tiles: 11 (obtained from counting the letters in probability)

Probability of picking the letter "i" the first time:

There are 2 letter "i's", and 11 total options, so the probability of picking an "i" is:

$\frac{2}{11}$

Probability of picking the letter "i" the second time:

We now have one less letter in the bag, as the first letter "i" was not replaced.

This means we now only have 1 letter "i", and 10 total options, so the probability of picking the last "i" is:

$\frac{1}{10}$

When you have two probabilities that are dependant on each other, you multiply them to get the probability of one, given that the other has happened.

Total probability:

$\frac{2}{11}*\frac{1}{10} = \frac{2}{110}$

Simplify by dividing by 2:

$\frac{1}{55}$
