Factor the expression below. x^2-64
a. (x+8)(x-8)
b. (x-8)(x-8)
c. (x+16)(x-4)
d. (x-16)(x-4)

a

Step-by-step explanation:

a² - b² = (a +b)(a - b)

64 = 8 * 8 = 8²

x² - 64 = x² - 8²    

          = (x +8)(x - 8)

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
