Step-by-step explanation:

well,

(y - 7)² = (y - 7)(y - 7)

remember how to multiply 2 expressions ?

you have to multiply every term of one expression with every term of the other expression and sum the results all up (incl. considering their individual signs, of course).

so, when we do the multiplication, we get

(y - 7)(y - 7) = y×y - 7×y - 7×y + (-7)×(-7) =

= y² - 14y + 49

and that is clearly different to y² - 49

FYI

y² - 49 is the result of

(y - 7)(y + 7)

because

y×y + 7×y - 7×y + (-7)(7) = y² - 49

lya took one hour to drive from his apartment to Philips Arena and back. The return drive took 8 minutes less than the trip to t
Phantasy [73]
An hour is 60 minutes.

The trip to the arena + The return drive = 60 mintues.

Since the return drive is 8 minutes shorter, if you added 8 minutes it would be the same length as the trip to the arena.

The return drive + 8 minutes = The trip to the arena

Let's represent these two equations with variables.

x + r = 60
r + 8 = x

What we do now is use substitution. Since r + 8 = x, we can replace x from the first equation with r + 8.

x + r = 60
r + 8 + r = 60
2r + 8 = 60
2r = 52
r = 26

Then use r in an earlier equation to find a.

r + 8 = x
26 + 8 = x
x = 34

To find the percentage, we have to multiply 25 and 8 by 4.

25x4 = 100

8x4 = 32

So, 8 out of 25 is 32%.
