I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.

 PLEASE SEE ATTACHED IMAGE.

 For this case the area is given by:

 A = (22 + x) * (28 + x) = 722

 Rewriting we have:

 616 + 22x + 28x + x ^ 2 = 722

 x ^ 2 + 50x + 616 - 722 = 0

 x ^ 2 + 50x - 106 = 0

 Solving the polynomial we have:

 x1 = 2.04

 x2 = -52.04

 We take the positive root:

 x = 2.04 inches:

 Answer:

 The width of the border to the nearest inch is:

Can someone help my sis on these questions? I dont remember how to do these things (part 1)
NNADVOKAT [17]

Answer:

Read below for each answer! (^-^)

Step-by-step explanation:

1: You got the first one right. The explanation does explain why but think about 0 as the surface of the water to better understand.

2: -3; it is between 2 and 4 with only one line through it meaning that it is -3.

3: 7. That's the greatest number both can divide into it.

4: The last one. Any positive number is greater than a negative one and peanut butter's freezing point is positive while the other one's is not.

5: You got it right again! -(-1) has two negatives. Two negatives (mostly) make a positive. So positive 1! Now describe that on a number line.

Hope this helps!
