sineoko [7]

Answer:

see explanation

Step-by-step explanation:

using the rules of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

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

then

$\sqrt{500}$

= $\sqrt{100(5)}$

= $\sqrt{100}$ × $\sqrt{5}$

= 10 × 2.24

= 22.4

-------------------------------

$\sqrt{0.5}$

= $\sqrt{\frac{50}{100} }$

= $\frac{\sqrt{50} }{\sqrt{100} }$

= $\frac{\sqrt{50} }{10}$

= $\frac{7.07}{10}$

= 0.707

Answer:

x = -1

Step-by-step explanation:

AB + BC = AC = 28

the way from A to C goes through B.

so, the total way of A to C is the sum of the way from A to B and then from B to C.

(5x + 10) + (2x + 25) = 28

7x + 35 = 28

7x = -7

x = -1
