Answer:

3a^2 - 6b + 2ab

Step-by-step explanation:

Add like terms together so shifting the equation a little to make it easier to add:

4a^2 - 7b + 2ab - a^2 + b

4a^2 - a^2 - 7b + b + 2ab

3a^2 - 6b + 2ab

Answer:

3a^2 - 6b + 2ab

Step-by-step explanation:

Put all the like terms together

(4a^2 - a^2) - (7b + b) + 2ab

then simplify

(4a^2 - a^2) = 3a^2

(-7b + b) = -6b

then rewrite

3a^2 - 6b + 2ab

Determine forms of exponential expressions please help

Irina-Kira [14]

Answer:

(36^t) / (6^(t^2)) is nonequivalent

(6^(t^2)) / (36^t) is equivalent

(6^(t^2)) * 36^t is nonequivalent

Step-by-step explanation:

We can use the exponential quotient law for this problem.

a^x / a^y = a^x - y

(6^(t^2)) / (6^2t) = (6^(t^2)) / (36^t)

In a certain Algebra 2 class of 29 students, 7 of them play basketball and 14 of them

Mariulka [41]

Answer:

<em>Two possible answers below</em>

Step-by-step explanation:

<u>Probability and Sets</u>

We are given two sets: Students that play basketball and students that play baseball.

It's given there are 29 students in certain Algebra 2 class, 10 of which don't play any of the mentioned sports.

This leaves only 29-10=19 players of either baseball, basketball, or both sports. If one student is randomly selected, then the propability that they play basketball or baseball is:

$\displaystyle P=\frac{19}{29}$

P = 0.66

Note: if we are to calculate the probability to choose one student who plays only one of the sports, then we proceed as follows:

We also know 7 students play basketball and 14 play baseball. Since 14+7 =21, the difference of 21-19=2 students corresponds to those who play both sports.

Thus, there 19-2=17 students who play only one of the sports. The probability is:

$\displaystyle P=\frac{17}{29}$

P = 0.59
