The age of a father is three times that of his son. In ten year's time their ages will add up to 68 years. If the son is x years

Elodia [21]

Answer:

46 and 22

Step-by-step explanation:

let the father b (f) and d son is (s)

f=3s.....(1)

(f+10) +(s+10)=68 .... (2)

substitute f=3s in equation (2)

we have

(3s+10)+(s+10)=68

4s+20=68

4s=68-20

4s=48

s=12 .......(3)

substitute (3) in (1)

f=3*12

which f=36

in 10 year time

f+10 =46

s+10=22

Can anybody help me on this?

Eduardwww [97]

Answer: second option.

Step-by-step explanation:

You need to descompose the radicand 8 and the radicand 50 into their prime factors:

$8=2*2*2=2^2*2\\50=2*5*5=2*5^2$

Then you can rewrite the expression:

$\sqrt{8}+\sqrt{50}$

$=\sqrt{2^2*2}+\sqrt{2*5^2}$

Since:

$\sqrt{a^2}=a$

You can simplify the expression:

$=2\sqrt{2}+5\sqrt{2}$

As the indices and the radicands are the same, you can make the addition:

$=7\sqrt{2}$
