Answer: 7 inches
Step-by-step explanation:
If x is the first piece, and the second piece is twice as long, then the second piece is 2x.
If the third piece is three times as long as the first piece, x, then the third piece is 3x.
The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.
42 = x + 2x + 3x
42 = 6x
42 = 6x
7 = x
The first piece is 7 inches long.

Answer:
x-2
Step-by-step explanation:
x3−3x2+3x−2/x2−x+1
=
x3−3x2+3x−2/x2−x+1
=
(x−2)(x2−x+1)/x2−x+1
=x−2
According to the rule of exponents 
, i.e. when two terms are in division with same base , we subtract the exponents
So
Or
x to the 3 fourteenths power
Step-by-step explanation:
To find slope : y2- y1 / x2 - x1
we have ( -5 , 1 ) which is ( x1 , y1 )
and ( -2 , 7 ) is ( x2 , y2 )
so; 7 - 1 / -2 - (-5)
6/3
= <u>2</u>
