X2+-4x+4=20 the final answer is 20!
To solve this...
Look at the number and determine how far it is from 3,000 and 4,000
Since 424 is closer to 0
And not 500... (which rounds up)
Your answer is going to be 3,000

Answer:
30
Step-by-step explanation:
Use part/whole proportions. 10/25 (15 + 10) = 12/x. Multiply 12 times 25 (300) = 10x (10 times x). 300 = 10x, isolate x by dividing both sides by 10 and you get 30 = x.
Answer:
(2,-9)
Step-by-step explanation:
Set the quadratic equal to zero.
Factor
Set each of these factors to zero
and
and
Plot the midpoint of the two values.
So the middle term is 2 and the other terms are 5 and -1.
Now the vertex is
So the vertex is
(2,-9)
