The following steps are used to rewrite the polynomial expression (x + 4y + 2)(x – 7y) Step 1: x(x - 7y) + 4y (x - 7y) + z(x -- 7y)
Step 2: x2 – 7xy + 4yx – 28y² + 2x - 7zy
Step 3: x2 – 7xy + 4xy – 28y2 + x2 – 7yz
Step 4: x2 – 3xy – 28y2 + x2 – 7yz
Identify the property used in each of the steps:

Tod does not have any cookies. david gives jeff 8 cookies. then he splits half of the cookies he has left with tod. david let’s c represent the number of cookies that he starts with. he finds the number of cookies that tod has is 1/2 the difference of c and 8. write an expression to represent the number of cookies that tod has.

Which function has the domain x> -11? y= x+ 11 +5 y= x-11 +5 y= x+5 - 11 y= x+5 + 11

One of the solutions to x2 - 2x – 15 = 0 is x = -3. what is the other solution? ox=-5 ox= -1 0 x=1 x = 5
