Equation 2.
length=3w, new length=2+3w, new width=1+w
New Perimeter=62=2(new length+new width)
62=2(2+3w+1+w) => 62=2(3+4w)
Answer:
x = 1 ± 
Step-by-step explanation:
Given
2x² - 4x = 10 ( divide through by 2 )
x² - 2x = 5
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 5 + 1
(x - 1)² = 6 ( take the square root of both sides )
x - 1 = ± ( add 1 to both sides )
x = 1 ± ← exact solutions
You move the decimal point 6 places to the right because the exponent is positive.
5.04 x 10^6 in standard form is 5040000.
Multiply both sides of the equation by (x+1), on the right hand side the denominator then goes away and on the left hand side you get (x+1)(x+1), foil that out then just solve for x
