Answer:

(7x+5)(7x-5)

Step-by-step explanation:

We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.

What percentage of 23 is 924

monitta

Well, the answer to the question in your picture is $1200.

If x is the original price, and we took 23%, or 0.23 from that, we are left with 77%, or 0.77 of the full price.

So 0.77x = 924
x = 924/0.77
x = 1,200

1200 - 0.23(1200) = 924

924 = 0.77x
