Answer:
A. (7n-1) (8n-1)
Step-by-step explanation:
56n^2 -8n-7n+1
56n^2 -8n -7n+1
Factor out 8n from the first group and -1 from the second group
8n (7n-1) -1(7n-1)
Factor out the (7n-1)
(7n-1) (8n-1)

Step-by-step explanation:
Answer:
140
Step-by-step explanation:
Given:
In the Stone Ridge apartment complex 35% of the apartments have one bedroom.
If there are 49 one bedroom apartments.
Question asked:
What is the total number of apartments at Stone ridge ?
Solution:
<u>Let total number of apartments at Stone ridge</u> =
Now according to question:
35% of the total apartments having one bedroom = 49
By cross multiplication:
By dividing both sides by 35
Therefore, total number of apartments at Stone ridge is 140
The mistake made by Enduro is that he is supposed to divide both sides by -4 instead of adding 4 to each sides
<h3>What are inequalities?</h3>
Inequalities are expressions that have unequal values, when compared
<h3>How to determine Enduro's mistake?</h3>
The inequality is given as
-4x > 120
When 4 is added to both sides, the inequality becomes
4 - 4x > 120 + 4
The above is not the solution to the inequality.
The solution is as follows:
We have:
-4x > 120
Divide both sides inequality by -4
x < -30
Hence, the mistake made by Enduro is that he is supposed to divide both sides by -4 instead of adding 4 to each sides

Answer:
The answer is 10m + 7n - 14
Step-by-step explanation:
Q = 7m + 3n
R = 11 - 2m
S = n + 5
T = -m - 3n + 8
[Q - R] + [S - T] is
[ 7m + 3n - (11 - 2m) ] + [ n + 5 - ( - m - 3n+8)]
Solve the terms in the bracket first
That's
( 7m + 3n - 11 + 2m ) + ( n + 5 + m + 3n - 8)
( 9m + 3n - 11 ) + ( m + 4n - 3)
<u>Remove the brackets</u>
That's
9m + 3n - 11 + m + 4n - 3
<u>Group like terms</u>
9m + m + 3n + 4n - 11 - 3
The final answer is
<h3>
10m + 7n - 14</h3>
