Question

Which shows 53^2 - 47^2 being evaluated using the difference of squares method?

53^2 - 47^2 = 2809 - 2209 = 600

53^2 - 47^2 = (53 + 47)(53 - 47) = (100)(6) = 600

53^2 - 47^2 = (53 - 47)2 = 62 = 36

53^2 - 47^2 = (2809 + 2209)(2809 - 2209) = 3,010,800

Answer 1

Difference of square: a^2-b^2=(a+b)(a-b)

Answer 2

53^2 - 47^2 = (53 + 47)(53 - 47)

Answer 3

yep :)

Not at all, say it :)

Answer 9

The graph of f(x) = x^2 is shifted 3 units to the right to obtain the graph of g(x). Which of the following equations best describes g(x)?

g(x) = (x + 3)^2

g(x) = x^2 - 3

g(x) = x^2 + 3

g(x) = (x - 3)^2

Answer 10

up: y=f(x)+c
down: y=f(x)-c
left: y=f(x+c)
right: y=f(x-c)

Where y denotes the new function and c denotes how many units it is translated to.

Answer 11

So what would it be? I don't get it

Answer 12

the fourth option :)

Answer 13

ah, alright thanks! :)

Answer 14
