Answer:
Option B. 4
Step-by-step explanation:
The given expression is x² + 4x + -----
We have to find a number which can be added in the expression to make it a perfect square trinomial.
x² + 2(2x) + 2²
= (x + 2)²
Therefore, if we add 4 in the given expression it becomes a perfect trinomial.
Option B is the correct option.
Okay, here we go.
With simpler decimals, this is a bit easier so I'll explain that first to make sure you get the basic idea.
Let's say you had a decimal for .75 and wanted to create the fraction mathematically. To do this you would:
First divide the decimal by 1 so .75/1
Then multiply be a multiple of 10 that eliminates the decimal so in this case 100
so you now have 75/100
When you simplify that fraction by dividing by 25, you of course get 3/4
Now on to your more complicated question:
Let's assign a variable to your repeating decimal so:
x=.1515151515
Now, let's identify the repeating digits, here they are .15
Move one set of the repeating digits in front of the decimal so now we get:
100x=15.1515151515
Now you have two equations, they are:
x=.1515151515
100x=15.1515151515
Combine the equations into one equation:
100x-x=15.1515151515-.1515151515
99x=15
15/99
simplify and you get 5/33
Answer:
Your answer is (0,-18)
Step-by-step explanation:
The Y Intercept is (0, -18) and the X Intercept is (18/5, 0)
I don’t know the first part but i think the second part would be 4^11
