$\sqrt{12} - \sqrt{48} =$

$\sqrt{12} - \sqrt{4 \times 12} =$

$\sqrt{4 \times 3} - \sqrt{4 \times 4 \times 3} =$

$\sqrt{ {2}^{2} \times 3 } - \sqrt{ {4}^{2} \times 3 } =$

$2 \sqrt{3} - 4\sqrt{3} =$

$(2 - 4) \sqrt{3} =$

$- 2 \sqrt{3}$

Answer:

QRT = 47, TRS = 133

Step-by-step explanation:

Since QRS is a line, QRT + TRS = 180.

$QRT+TRS=180\\3x+5+10x-7=180\\$

Then, solve for x. Combine like terms.

$13x-2=180\\13x=182\\x=14$

Then, plug in 14 for x.

$1. (3*14+5)\\\\QRT = 47\\\\2. (10*14-7)\\\\TRS = 133$
