Answer:
Step-by-step explanation:
Given :
l + m + n = 9
l²+ m² + n²= 31
l + m + n = 9
On squaring both sides
(l + m + n)²= 9²
(l²+m²+n²+2(lm+mn+nl) = 81
31 +2(lm+mn+nl) = 81
2(lm+mn+nl) = 81 - 31
2(lm+mn+nl) = 50
(lm+mn+nl) = 50/2
(lm+mn+nl) = 25
Hence, the value of (lm+mn+nl) = 25
Answer:
Step-by-step explanation:
See attachment for complete question
From the question, we understand that one shrub must be at both ends.
Taking the first as a point of reference, we're left with:
Substitute 10 for n and d for distance
Hence:
answers the question
Because it states that for every amount of something there is a certain amount based on something else. For example, for every apple i have, i will have two bananas. This will go into the ratio 1:2. Hope this helps☺
