Answer:
7
Step-by-step explanation:
7 because it's not asking for squares it asking for cubes
I think it is C-two real solution
I hope this helps you
x^2/2+12x/2+10/2=0
x^2+12x+10=0
ax^2+bx+c=0
disctirminant =b^2-4ac
x1,2=-b (-,+) square root of disctirminant /2a
a=1 b=12 c=10
disctirminant = 12^2-4.1.10=144-40=104
x1= -12+square root of 104/2
x2= -12- square root of 104/2
Answer:
18
Step-by-step explanation:
The length of side AC can be found by counting the squares between AC: 8.
The length of side BC can be found using the Pythagorean Theorem. B is 3 units to the right of C and 4 units above C. Thus:
|BC| = √(3² + 4²) = √25 = 5.
|AC| has the same length: 5.
Thus, the perimeter of this triangle is 5 + 5 + 8, or 18.
