Step-by-step explanation:
by using similarity and enlargement
10/8 = 7+y/7
70=56+8y
8y=14
y= 7/4
10/8 = 5+x/5
50=40+8x
x = 8/10 = 4/5
There are 0.34 kiloliters in 34 dekaliters.
The two roots a + sqrt b and a - sqrt b are called conjugate radicals.
<u>Solution:</u>
Given that the two roots a + sqrt b and a - sqrt b are called ______ radicals.
Now let us write the each of the given two radicals in mathematical form.
So, first radical ⇒ a + sqrt b ⇒
[ since sqrt means square root]
Now second radical ⇒ a - sqrt b ⇒ 
We have to find the relation between 
Now, if observe
is conjugate of 
[ where radical is eliminated]
Hence, the two roots a +sqrt b and a- sqrt b are called conjugate radicals
I don't think you have the correct options. 9/12 + 6/12 = 15/12. To simplify, you divide each value by 3 and get 5/4, which, as a mixed number, would be 1 1/4, and neither 5/4 or 1 1/4 is an option. I hope this helps!
Answer:
I think this is the right answer
C=12
P=3
