It need to be more clear for me to read
Answer: 0
Step-by-step explanation:
The disciminant \Delta tells you how many real solutions a quadratic equation has, depending on its sign:
\Delta>0\implies\text{2 solutions}\\\Delta=0\implies\text{1 solution}\\\Delta<0\implies\text{no solutions}
Answer:
5*3=5+3-1 (acc to question)
5*3=7
Answer:
<em>1.1n</em>
<em>0.6p</em>
<em>0.3b</em>
Step-by-step explanation:
<u>Simplifying Like terms</u>
Like or similar terms are those who have the same letters raised to the same power. For example, 5ab, -6ba, 0.6ab are like terms.
Terms like 5xy, -6xz,
are not similar because they have different letters of powers.
The terms 1.6n-0.5n are similar and they can be simplified by operating their coefficients: 1.6-0.5=1.1. Thus
1.6n - 0.5n = 1.1n
Similarly, we can simplify 0.9p-0.3p. Operating 0.9-0.3=0.6 gives the result:
0.9p - 0.3p = 0.6p
Finally:
b - 0.7b = (1 - 0.7)b = 0.3b
Results:
1.1n
0.6p
0.3b
