Answer:
The number to be added is 81/4
Step-by-step explanation:
To get the number, we look at the coefficient of x
In this case, we have it as -9
we divide this by 2
It gives (-9/2)
We square this value and add it to both sides
This would be
(-9/2)^2 = 81/4
It is this number we will add to both sides of the equation
The answer is d.
Explanation:
To start with, classify the first two terms and factor out the common factor. i.e m is a common factor of m2-6m. By factoring it out we get m(m-6).
Follow the same procedure for terms three and four. ie
6 is a common factor of 6m-36. By factoring out, 6(m-6)
Regrouping
m(m-6)+6(m-6)
By factoring out (m-6), we get:
(m-6)(m+6)
Answer:
w=186-2t
Step-by-step explanation:
you can solve this too
just do w=186
Answer:
5/18
Step-by-step explanation:
Let's say the original packaging was 1 lb of packaging for $1.
The cost was $1/lb.
Then the weight went down by 10% and the price went up by 15%.
Now 0.9 lb of packaging cost $1.15.
The new unit cost is $1.15/(0.9 lb)
The difference is
$1.15/(0.9 lb) - $1/lb =
= $1.15/(0.9 lb) - $0.9/(0.9 lb)
= $0.25/(0.9 lb)
=$25/(90 lb) = $5/(18 lb)
The price went up by 5/18.
