I think it’s 230+x is greater than or equal to 500.
I don’t have the greater than or equal sign in my phone lol
Answer:
Umm what do <em>I</em> answer there is nothing there
Step-by-step explanation:
You can get all the terms on one side, and then solve for x by any means:

Factor out a -2:

Factor this equation:

I will use the AC method. To use it, first multiply a and c (in ax^2 + bx +c):

Now, look for two numbers that multiply to -12 and add to -11. Obviously these numbers are -12 and 1. (-12*1 = -12 and -12+1 = -11). Now, because of rules, you set it up in a Punnett square:
4x^2 -12x
x -3
Now, we find common factors of the terms in rows:
_x_______-3__
4x| 4x^2 -12x
1 | x -3
So, you can use this to write an equivalent expression to the quadratic given:

Now, we known the factors are (solve for x):
3 and -1/4.
Step-by-step explanation:
102*100=10200
10200÷126=80.95
So the third one is correct
Answer:
940
Step-by-step explanation:
188
<u>× 5</u>
940
--------------------------------------------------------
8 * 5 = 40
Carry the 4 to the next 8
8 * 5 = 40
Add the 4 to the 40
40 + 4 = 48
Carry the 4 to the 1
1 * 5 = 5
Add the 4
5 + 9
= 940
