Take a quadratic equation in standard form:
If there exists a sum of two numbers that equal b, whose addends produce a product that equals c. You can rewrite the quadratic as a product of two binomials.
For example take
When thought through throughly, -5 had addends, -2 and -3 that produce 6 when multiplied
Thus, we can rewrite the quadratic as.
Answer: They originally thought they were paying £1680
Step-by-step explanation:
1680+12.5%1680= 1890
1680+210=1890
1890=1890
The factored expression which represents the net change in the number of blog subscriptions over 10 months is :
- 3(11 - 7) + 4(-8)
- Hence, the net change is -20
Change : -8, 11, -7, -7, -7, -8, -8, -8, 11, 11
To factor the values in the change variable :
-7 has a frequency of 3
-8 has a frequency of 4
11 has a frequency of 3
Values having the same frequency can be factored together :
Hence, we have ;
3(11 - 7) = 3(11 - 7) = 3(4) = 12 - - - - (1)
-8 having a value of 4 can be factored thus ; 4(-8) = -32 - - (2)
Joining both equations :
3(11-7) + 4(-8)
3(11 - 7) + 4(-8)
3(4) + 4(-8)
12 + (-32)
= - 20
Therefore, the factored expression for the net change in subscription is 3(11-7) + 4(-8)

Answer: Efficiency metrics
Step-by-step explanation:
From the question, we are informed that Cory Randle tracks the performance of his system by tracking the response time it takes to respond to Twitter posts mentioning the news station, and as the speed and accuracy of content that are posted on numerous websites and social media sites.
The type of metrics that Cory is using to measure his system is efficiency metrics. It should be noted that this is to determine how efficiently a company is using its resources whether the resources are being used well or they're inefficiently used and wasted. The metrics can also be used to determine how effective management is.
Answer:
angle b = 25°
for angle A = 180 - 50 (ie 25 + 25)
angle a =130°
