and the formula for that is A=lw
so you have a length of 15.5.     
Put those in and you get 170.5=15.5w.
you divide 170.5 by 15.5 and get 11.
the Width is 11.

Solve for x^2-2x+1=0
seraphim [82]

Answer:

x=1

Step-by-step explanation:

x^2-2x+1=0\\

We will start by using the quadratic formula.

\frac{-(-2)+-\sqrt{(-2)^2-4(1)(1)}}{2(1)}

We will simplify that and get:

\frac{-(-2)}{2(1)}

So our answers would be:

x=1

Solve x^2 + 4x + 8 = 0
Mkey [24]

Answer:

x = -2 + 2 i or x = -2 - 2 i

Step-by-step explanation:

Solve for x:

x^2 + 4 x + 8 = 0

Subtract 8 from both sides:

x^2 + 4 x = -8

Add 4 to both sides:

x^2 + 4 x + 4 = -4

Write the left hand side as a square:

(x + 2)^2 = -4

Take the square root of both sides:

x + 2 = 2 i or x + 2 = -2 i

Subtract 2 from both sides:

x = -2 + 2 i or x + 2 = -2 i

Subtract 2 from both sides:

Answer:  x = -2 + 2 i or x = -2 - 2 i
