Do you mean 7?
You need to multiply each like term differently ( 1. Coefficient, 2. M term, 3. N term, and 4. O term)
1. The coefficients are 4 and 7, and as you have already solved, that equals to 28.
2. The m terms are (m • m) because there is one m in (4mno) and one m in (mn). m • m would equal to m^2.
3. The n terms are (n • n^2 •n) because there is one n in (4mno), n^2 in (7n^2o^2), and one n in (mn). They would equal n^4.
4. The o term would stay as o^2 as there are not other o terms.
To piece it all together, your answer would be 28m^2n^4o^2, or 28 • m ^2 • n^4 • o^2.
Answer:
Step-by-step explanation:
Given data:
Mass of the liquid ( m ) = 550 kg
Volume of the liquid ( v ) = 680 litre
= 680*10-3 m3
= 0.68 m3
Now, Density of the liquid = (m/v)
= (550 kg )/(0.68 m3)
= 809 kg/m3
Answer:
(a) 0
(b) -3/26
Step-by-step explanation:
(a)
We essentially plug 1 in for x and 2 in for y.
Our expression is 
, so making the correct substitutions yields:
So, the answer for part (a) is 0.
(b)
Again, we're now plugging in 1 for x and 5 for y:
So, the answer for part (b) is -3/26.
