What is the factored form of 64g^3+8

vivado [14]

$\bf \textit{difference and sum of cubes}
\\\\
a^3+b^3 = (a+b)(a^2-ab+b^2)\qquad
(a+b)(a^2-ab+b^2)= a^3+b^3 
\\\\
a^3-b^3 = (a-b)(a^2+ab+b^2)\qquad
(a-b)(a^2+ab+b^2)= a^3-b^3\\\\
-------------------------------\\\\
64g^3+8\implies 4^3g^3+8\implies (4g)^3+2^3
\\\\\\
(4g+2)[(4g)^2-(4g)(2)+2^2]\implies (4g+2)[(4^2g^2)-8g+4]
\\\\\\
(4g+2)(16g^2-8g+4)$

Answer:

Step-by-step explanation:

1.From the given triangle, ABC, using the proportionality theorem, we get

$\frac{FA}{CA}=\frac{EF}{BC}$

⇒ $\frac{8}{40}=\frac{5}{x}$

⇒ $x=25ft$

Thus, the height will be 25 feet.

2.

Statement Reason

1.∠C≅∠E Given

2. ∠ABC≅∠DBE Vertically opposite angles

3. ΔABC is similar to ΔDBE AA similarity rule.
