The formula of a midpoint of AB:

$M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)$

We have:

G(b; 0); F(3b; 2b)

substitute:

$M_{GF}\left(\dfrac{b+3b}{2};\ \dfrac{0+2b}{2}\right)\to M_{GF}(2b;\ b)$

Answer: (2b, b)

Factor using the identity: a3 + b3 = (a + b)(a2 – ab + b2) 8z3 + 27

vivado [14]

Answer: this is our required factor i.e.

$8z^3+27=(2z+3)(4z^2-6z+9)$

Explanation:

Since we have given that

$8z^3+27$

As we know the identity , which says that

$a^3+b^3=(a+b)(a^2-ab+b^2)$

So, we can use this here ,

$8z^3+27=(2z)^3+3^3\\\\=(2z+3)((2z)^2-2z\times 3+3^2)\\\\=(2z+3)(4z^2-6z+9)$

Hence this is our required factor i.e.

$8z^3+27=(2z+3)(4z^2-6z+9)$

What expression is equivalent to 5 to the 6th power?PlZZZ HElP

Akimi4 [234]

Answer:

$5^6 = 125 * 125$

Step-by-step explanation:

The given expression can be represented as:.5⁶

Required

Find equivalent expression

$5^6$

Express 6 as 3 + 3

$5^6 = 5^{3+3}$

Apply the following law of indices

$a^{m+n} = a^m * a^n$

So, we have:

$5^6 = 5^{3} * 5^{3}$

Express $5^3$ as 125

$5^6 = 125 * 125$

Hence, option (b) is equivalent
