Answer:

Step-by-step explanation:

6x² + 4(x² - 1) = 6x² + 4*x² - 4*1

           = 6x² + 4x² - 4    

            = 10x² - 4

4a⁵ - 2a⁵ + 4b +b = 2a⁵ + 5b

You have to add/ subtract the like terms

4a⁵ and 2a⁵ are like terms

4b and b are like terms

WARRIOR [948]

Answer:

120 students students could be expected to not be wearing a jacket

Step-by-step explanation:

Based on this, we can work with the assumption that 3/5 of the students that entered the stadium were wearing jackets.

Given that the total population of students that attended the game is 300

This means that 3/5 of the 300 = 180 students.

180 students were estimated to be wearing jackets.

The number of students that were without jackets is 300 - 180 = 120 students

Alja [10]

Step-by-step explanation:

B. False

they cannot be written as 10xy but only in 5x+5y

x and y will only become together if they are multiplied

as you can see there's a plus sign

you can add them if it is in 5x+5x (or) 5y+5y but never as in 5x+5y
