Answer:

Step-by-step explanation:

If the side of the shape is increased by 3/2 then the total distance around the shape will be 3/2 bigger.

Example: If the pentagon has side length 2 then it becomes 2*3/2 = 6/2 = 3.

The original perimeter was 2+2+2+2+2 = 10.

The new perimeter is 3+3+3+3+3 = 15.

Did you notice that $\frac{15}{10}=\frac{3}{2}$ ? J is correct.

$- 104 \geqslant - 8b - 8$

put -8 near -104

$- 104 + 8 \geqslant - 8b$

$- 96 \geqslant - 8b$

b will be alone.

$\frac{ - 96}{ - 8} \geqslant \frac{ - 8b}{ - 8}$

$b \geqslant 12$

Answer A

$3m - 7 > - 4$

$3m > - 4 + 7$

$3m > 3$

$\frac{3m}{3} > \frac{3}{3}$

$m > 1$

Answer A

İf

$m \geqslant 1$

The answer would be D

But answer A

$- 4x + 4 > - 16$

$16 + 4 > + 4x$

$20 > 4x$

$\frac{20}{4} > \frac{4x}{4}$

$x < 5$

Answer B

We learnt this way in Turkey.
