180 -134 = 46 is PRQ
46 x 2 = 92 is POQ acute angle
360 - 92 = 268 is POQ reflex angle
Answer:
Step-by-step explanation:
hello :
x²-3x-10=0 means : (x-5)(x+2)=0
x-5=0 or x+2=0
conclusion two solutions : 5 and -2
These are the formulas right?.. I hope so, anyways..
- f(n)= 2^(n-1) -1
- g(n)=3n+6
f(7)=2^{7-1}-1 - f(7)=2^{6}-1 - f(7)=64-1 - f<u>(7) = 63
</u>
g(10)=3\X 10+6 - g(10)=30+6 - g<u>(10) = 36</u>
= <u>f(7)>g(10)</u>
I hope that it helped..
