Answer:

Step-by-step explanation:

7m ÷ 2 = 3.5m
Part A: New square is 3.5-meter by 3.5-meter
The original square's perimeter is 7x4=28-meter.
The new square's perimeter is 3.5x4=12-meter
Part B: The ratio is 12:28 or 3:7
The original square's area is 7²=49 meter²
The new square's area is 3.5²=12.25 meter²
Part C: The ratio is 49:12.25

V125BC [204]

Answer:

Step-by-step explanation:

Using the rule of radicals

$\sqrt{\frac{a}{b} }$ = $\frac{\sqrt{a} }{\sqrt{b} }$

$\sqrt{a\\}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Given

$\sqrt{\frac{6}{x} }$ × $\sqrt{\frac{x^2}{24} }$

= $\frac{\sqrt{6} }{\sqrt{x} }$ × $\frac{x^2}{24}$

= $\frac{\sqrt{6} }{\sqrt{x} }$ × $\frac{x}{2 \sqrt{6\\} }$

Cancel $\sqrt{6}$ on numerator/ denominator

= $\frac{1}{\sqrt{x} }$ × $\frac{x}{2\\}$

= $\frac{1}{\sqrt{x} }$ × $\frac{(\sqrt{x})^2 }{2}$

Cancel $\sqrt{x}$ on numerator/ denominator, leaving

= $\frac{\sqrt{x} }{2}$ → D
