Hi! I just took the test and the photo below is the correct answer. Hope this helps and have a great day :)
Answer:
look its really simple like if there is written the father age is two times than its son and its is also said sum of their age becomes 25 then
Step-by-step explanation:
solution,
let father and son age be x and y
2x =y ---------------(i)
x+y=25----------------(ii)
now,
putting the value of y in equation two we get,
x+(2x)=25
3x=25
x=25/3
x=8 yrs ( using round off)
again,
2x = y
2×8=y
16=y
therefore, father age is 16 and son age is 8

Hello! And thank you for your question!
First move all the terms to one side:
<span>x^<span><span>2</span><span></span></span></span>−4x−9−29=<span>0
</span>
Then simplify x^2−4x−9−29:
<span><span><span>x<span><span>^2</span><span></span></span></span>−4x−38=0</span><span>
Then use the quadratic formula:
x = 4 + 2</span>√42 over 2 , 4 - 2√42 over 2
Finally simplify:
x = 2 + √42, 2 - √42
Final Answer:
x = 2 + √42, 2 - √42
