I would draw the triangle then it would be easier to answer. It is not an equilateral because it is not equal on all sides. Perhaps scalene because all the sides are not the same.
Answer:
C: x^4+6x^3-12x-72
Step-by-step explanation:
For the function : f(x)=√x^2+12x+36
It can be factorized to
f(x)=√(x+6)²
=x+6
f(x)*g(x)
=(x+6)(x^3-12)
Expand the brackets
=x^4-12x+6x^3-72
rearrange the numbers
x^4+6x^3-12x-72
Answer: g<22.5
Step-by-step explanation:
Isolate the variable by dividing each side by the factor that don’t contain the variable.
A is the correct answer buddy.
