The following steps are used to rewrite the polynomial expression (x+4y+z)(x-7y).
Step 1: x(x-7y)+z(x-7y)
Step 2: x^2-7xy+4yx-28y^2+zx-7zy
Step 3: x^2-7xy+4xy-28y^2+xz-7yz
Step 4: x^2-3xy-28y^2+xz-7yz
Identify the property used in each of the steps:
Step 1:
Step 2:
Step 3:
Use Distributive, Commutative, Associative.

ithink is y=3

Step-by-step explanation:

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

do you mean add both of the equations together

because if you do the answer is 10x-5
