i need the answers too this i have too get my grade up

CHECK AT THE BACK OF YOUR BOOK

Step-by-step explanation:

THE ANSWER IS 0

x ^ 2–2x + 1

by splitting this equation

x ^ 2 - x -x + 1

there are a two terms x ^ 2 - x and - x + 1

we take x is common from first and -1 is common from second

x ( x - 1 ) and -1 ( x-1 )

the quadratic roots are (x-1) and (x-1)

x - 1 = 0

x = 1 in both

Therefore , the quadratic roots are 1 , 1 .

the answer is B cause I just took a test with this question

let

x----------> number of square jam sandwiches of Ken in the side x of rectangle

y---------> number of square jam sandwiches of Ken in the side y of rectangle

A1-------------> total number of square jam sandwiches of Ken

A2-------------> total number of square jam sandwiches of Sara

we know that

A1=xy

A2=[(x+2)(y+2)-xy]

A1=A2

xy=[(x+2)(y+2)]-xy------------ > xy=xy+2x+2y+4-xy

xy-2y=2x+4-------- > y=[2x+4]/[x-2]

testing different values of x to get a pair of whole numbers--> see the table attached I find 2 solutions

1) x=3 and y=10

A1=3*10=30

A2=30

total number of sandwiches of Ken------ > 30

total number of sandwiches of Sara------ > 30

2) x=4 and y=6

A1=4*6=24

A2=24

total number of sandwiches of Ken------ > 24

total number of sandwiches of Sara------ >24
