Answer:

6x + 12

Step-by-step explanation:

Each term in the parenthesis is multiplied by the 3 outside

3(2x + 4)

= (3 × 2x) + (3 × 4)

= 6x + 12

Represent the following expressions as a power of the number a (a≠0): c ((a2)−2)5÷(a4a)3

s2008m [1.1K]

Answer:

1/a²⁷

Step-by-step explanation:

Given: $\frac{((a^2)^{-2})^5}{a^4.a^3}$

We know that when the bases are same the powers can be added. i.,e.,

(xᵃ)ᵇ = x ⁽ᵃ ⁺ ᵇ⁾

⇒ $\frac{((a^2)^{-2})^5}{a^4.a^3} \implies \frac{(a^2)^{-10}}{a^7}$

$\implies \frac{a^{-20}}{a^7} = a^{-20 - 7} = a^{-27}$

Also, $\frac{x^a}{x^b} = x^{a - b}$

This is nothing but, $\frac{1}{a^{27}}$ .

Note that $a$ cannot be zero here. The condition is provided in the question as well.

How did they get that vertex

Nataly_w [17]

Answer:A vertex (or node) of a graph is one of the objects that are connected together. The connections between the vertices are called edges or links. A graph with 10 vertices (or nodes) and 11 edges (links).

Step-by-step explanation: (The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.
