I NEED HELP RN PLEASEEEE ITS AN EMERGENCY!!
strojnjashka [21]

Answer:

The answer is C) 12\sqrt{2}.

Step-by-step explanation:

For a real number a,

\sqrt{a} \cdot \sqrt{a} = a.

In other words, multiplying a square root by itself gets rid of the square root.

How does this rule apply here?

24 = 2\times 12.

Similarly,

\sqrt{24} = \sqrt{2}\times \sqrt{12}.

That is:

\begin{aligned}\sqrt{24}\times \sqrt{12} &= (\sqrt{2}\times \sqrt{12}) \times \sqrt{12}\\&=\sqrt{2}\times (\sqrt{12}\times \sqrt{12}) && \begin{array}{l}\text{By the associative property}\\\text{of multiplication}\end{array}\\&=\sqrt{2} \times 12\\ &= 12\sqrt{2}\end{aligned}.

Please help I need help I will mark brainliest
Sedaia [141]

a:

Just divide both sides by 7. Since 7 is positive, you don't need to change the inequality sign:

7j>77\iff j>11\}

In set notation, we write

\{j \in \mathbb{R}\ :\ j>11

b:

Subtract 9 from both sides:

17\leq x+9 \iff 8\leq x

In set notation, we write

\{x \in \mathbb{R}\ :\ x\geq 8\}
