Answer 1

.

2.a) |x-√12| =√3

|x-2√3|=√3

x-2√3=√3

x=2

b)x√27=√300-√48

3x√3=10√3-4√3

3x√3= 6√3

x=2

3.

3a-2b=8|×(-4)

4a+3b=5|×3

-12a+8b=-32

12a+9b=15

/+17b=-17

b=-1

=> 3a+2=8

3a=6

a=2

4.

$lm = \frac{16}{2} \\ lm = 8 \: cm$

$h = 3 \\ aria = \frac{16 \times 3}{2} \\ = \frac{48}{2} \\ = 24 \: {cm}^{2}$

$ac = \sqrt{64 + 9} \\ = \sqrt{73} \\ ao = \frac{2}{3} \times ac \\ ao = \frac{2 \sqrt{73} }{3}$
