3x^(2)+4x-3x-5-2=0
3x^(2)+x-7=0
Discriminat= b^(2)-4ac= 1^(2)-4(3)(-7)= 1-12(-7)=1+84=85
The discrimination is bigger than 0 (delta>0) therefore there are 2 real solutions

Answer:
0.274g/cm^3
Step-by-step explanation:
density = mass / volume
so d = 575.4 / 210
d = 0.274g/cm^3
The simplified expression would be 3s + 15.
In order to find this we need to write an equation for the longest side. Since it's 3 more than twice as much as the smallest side (s), we can express it as 2s + 3. Now we simply add all 3 together and simplify.
2s + 3 + 12 + s -----> simplify
3s + 15
