Hello!

Answer:

\boxed{\boxed{\bf THEME:\:EQUATIONS\:\:WITH\:\:PARENTHESIS}}

Es\:\:-4x^2+6x+4

Step-by-step explanation:

(x^2 + 5x + 2) - (5x^2 - x - 2)

◈We remove the parentheses:

x^2+5x+2-5x^2+x+2

◈We subtract "x²" and "5x²":

-4x^2+5x+x+2+2

◈We add up "5x" and "x":

4x^2+6x+2+2

◈We add up "2" and "2":

-4x^2+6x+4

Answer:

{ \tt{( {x}^{2} + 5x + 2) - (5 {x}^{2} - x - 2)  }} \\  = { \tt{(1 - 5) {x}^{2}  + (5 + 1)x + (2 + 2)}} \\  = { \tt{ - 4 {x}^{2} + 6x + 4 }} \\  = { \tt{ - 2(2 {x}^{2} - 3x - 2) }}

The course grade in a statistics class is the average of the scores on five examinations. Suppose that a student's scores on the
nadya68 [22]

Answer:

84 is the highest possible course average

Step-by-step explanation:

Total number of examinations = 5

Average = sum of scores in each examination/total number of examinations

Let the score for the last examination be x.

Average = (66+78+94+83+x)/5 = y

5y = 321+x

x = 5y -321

If y = 6, x = 5×6 -321 =-291.the student cannot score -291

If y = 80, x = 5×80 -321 =79.he can still score higher

If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.

If y= 100

The average cannot be 100 as student cannot score 179(maximum score is 100)
