Answer:
(w-12)(w+12)
Step-by-step explanation:
Using the identity
a^2-b^2=(a-b)(a+b)
now,
w^2-144=(w)^2-(12)^2=(w-12)(w+12)

Answer:
Elgas is 35.
Step-by-step explanation:
Let's set up an equation.
Alvin is 7 years younger than Elgas.
A = E - 7
The sum of their ages is 63.
A + E = 63
Let's use substitution.
Plug in the first equation of A into the second equation.
A + E = 63
(E - 7) + E = 63
Combine like terms.
2E - 7 = 63
Add 7 to both sides.
2E = 70
Divide both sides by 2.
E = 35
Elgas is 35.
Hope this helps!
A, C, and E will be your correct answers! When 16:28 is simplified we get 4:7. When we simplify 20:35 we get 4:7. therefore, A, C, and E will be correct!
