Answer:

Step-by-step explanation:
given
, x ≠ - 1
The x ≠ - 1 means that x cannot take the value of - 1 as this would make the denominator equal to zero which would make the fraction undefined.
Factor the numerator/ denominator
8x² - 8 = 8(x² - 1) ← factor out 8 from both terms
x² - 1 ← is a difference of squares, hence
8x² - 8 = 8(x - 1)(x + 1)
4x + 4 = 4(x + 1) ← factor out 4 from both terms
Thus the fraction now simplifies to
Cancel the 8 and 4 by 4 and cancel the factor (x + 1), leaving
= 2(x - 1) = 2x - 2 ← in the form ax + b

Step-by-step explanation:
Since we have given that
Cost of soccer balls = $15
Cost of baseball = $6
Cost of sweat socks = $5
a) Mr. Tonkery bought x number of soccer balls and 3 base balls .
So, our algebraic expression will be
b) Dennis, Eddie and Felix are on a base ball team. They each bought a baseball and x pair of sweat socks .
Since there are 3 members in a base ball team ,
Number of base ball they will purchase is given by
Number of sweat socks they will bought is given by
Total number they will purchase is given by
Hence, both answers will be
