Answer:
4√2 or 5.66
Step-by-step explanation:
x² + x² = 8²
=> 2x² = 64
=> x² = 32
=> x = √32 = 4√2 or 5.66
Y ( 2 ) = - 5.131 · 2² + 31.821 · 2 - 3.3333 =
= - 5.131 · 4 + 63.642 - 3.3333 = -20.524 + 63.642 - 3.3333 = 39.78 ≈ 40
Answer: B ) 40.
Answer: -10.5, -3.5, -8.75
Or 3 depending on how you solve
Step-by-step explanation: x = g (x) therefore where it crosses the X intercept those are your answer

so we have a 33, namely two real solutions for that quadratic.
usually that number goes into a √, if you have covered the quadratic formula, you'd see it there, namely that'd be equivalent to √(33), now 33 is a prime number, and √(33) is yields an irrational value, specifically because a prime number is indivisible other than by itself or 1.
so 33 can only afford us two real irrational roots.
