Hi, The answer is 2x^2-8x+12, because when you subtract the polynomial with the answer you will get x^2-4
Answer:
From the survey, the following apply to both Junior and Seniors who were asked about their plan towards attending college:
C. Given the student plans to attend college, the probability the student is a junior is 68%.
D. Given the student is a junior, the probability the student plans to attend college is 68%.
F. Events "is a senior" and "plans to attend" are independent.
B. The probability the student plans to attend college is 70%.
Step-by-step explanation:
This is some simple Algebra
So it's 4x+16=-2
We subtract 16 from both sides
4x=-18
Sivide both sides by 4
X=-4.5
If you need more of an explanation I am happy to elaborate
Answer:
Step-by-step explanation:
Given the sequence :
23, 19, 13, 5, -5.......
From the sequence, the common difference is unequal, as their is a constant Increment in the difference after successive numbers.
19 - 23 = -4
13 - 19 = -6
5 - 13 = -8
-5 - 5= -10
Hence an constant difference of - 2 after each successive difference.
Hence, this is a quadratic sequence
With the formula
an² + bn + c
Answer:
x-60
Step-by-step explanation:
You have to factor out the quadratic.
You know that one of the factors is x-40.
To factor:
Find a number that when added to -40, gives you -100, and also when multiplied, gives you 2400.
That such number is -60.
Add an x before it, and you get (x-60)
