Hi can u help me with my hw

1) w = 14/3
Steps:
1) Multiply the numbers
5w - 8/3 = 4w + 2
2) Add 8/3 to both sides of the equation
5w - 8/3 + 8/3 = 4w + 2 + 8/3
3) Simplify
A. Add the numbers
5w = 4w + 2 + 8/3
B. Add the numbers
5w = 4w + 14/3
4) Subtract 4w from both sides of the equation
5w - 4w = 4w +14/3 - 4w
5) Simplify
A. Combine like terms
1w = 4w + 14/3 - 4w
B. Multiply by 1
w = 4w + 14/3 - 4w
C. Combine like terms
w = 14/3
2) ( x - 7 ) ( x + 7 )
Steps:
1) Use the sum-product pattern
x² + 7x - 7x - 49
2) Common factor from the two pairs
x (x + 7) = 7 (x + 7)
3) Rewrite in factored form
(x-7) (x+7)
3) [tex]3x^{4} y^{\frac{3}{2} }[/tex]
Steps:
[tex]9^{\frac{1}{2} }( x^{8} )^{\frac{1}{2} (y^{3} )\frac{1}{2}[/tex]
