Answer:
2/7
Step-by-step explanation:
7x/7=2/7
Simplify:Cancel terms that are both the numerator and denominator
Solution: 2/7
This is a polynomial of degree 4, because you have 4 roots real or imaginary:1st) x= 5 →(x-5)=0
2nd) x = - 3→(x+3) =0
3rd) x = -1+3i →(x+1-3i) = 0
and the 4th one that is not mentioned which is the conjugate of
-1+3i, that is -1-3i (in any polynomial if a root has the form of a+bi, there is always a conjugate root = a-bi)
4th) x= -1-3i→(x+1+3i) = 0
Hence the polynomial =(x-5)(x+3)((x+1-3i)(x+1+3i)
Solving the above will give you (unless I am mistaken, pls recalculate):
x⁴-9x²-50x-150<u />
I don’t know sorry mannnn
Use the Pythagorean Theorem Formula
a^2+b^2=c^2
a=12
b=9
12^2+9^2=c^2
144+81=c^2
225=c^2
Square root 225 and c^2
c=15
Answer: c=15
Step-by-step explanation:
you can with a calculator
but to make it easier all the fraction should be in improper form to make subtraction easier
plsss mark me brainliest
