What are the restraints on this equation: ((x-3)/x^2-64)+11/x^2-64

answer:

x=11

step-by-step explanation:

step-1 : multiply the coefficient of the first term by the constant   1 • -55 = -55

step-2 : find two factors of   -55   whose sum equals the coefficient of the middle term, which is   -6 .

      -55     +     1     =     -54

      -11     +     5     =     -6     that's it

step-3 : rewrite the polynomial splitting the middle term using the two factors found in step 2 above,   -11   and   5

                    x2 - 11x + 5x - 55

step-4 : add up the first 2 terms, pulling out like factors :

                    x • (x-11)

              add up the last 2 terms, pulling out common factors :

                    5 • (x-11)

step-5 : add up the four terms of step 4 :

                    (x+5)   •   (x-11)

            which is the desired factorization

yes

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
