Idk what the hell all that is but x = 1.802775637731995
4x^2 - 13 = 0
4x^2 = 13
13/4=3.25
x^2 = 3.25
x = ~1.8
Answer:
the top are right im not sure about bottom
<span>integers are numbers that we get from adding and subtracting the number 1. Zero also belongs to integers .
</span><span>example
3 = 1+ 1 + 1
3 = 1 + 1 + 1 +1 - 1
0 = 1 + 1 - 1 - 1
- 4 = -1 - 1 - 1 -1
- 4 = 1 - 1 -1 - 1 - 1
</span><span>In this way you can get infinitely large number of total positive , negative and zero</span>
Answer:
7/2
Step-by-step explanation:
1/8 + 1/4, you must change the denominator so that they are the same.
So that would mean 1/8+ 1/8, but since the denominator for the second one was 1/4 we must multiply the top by 2. So it becomes 1/8+2/8. You then change the denominator for the rest of them like this and it becomes 1/8+2/8+3/8+4/8+6/8+7/8 which simplified equals 7/2.
