Answer: 227
Step-by-step explanation:
4x^4 = (4*4*4*4) 256
4x^2 = (4*4) 16
256 + 16= 272
272 - 45 = 227
Rounded to the nearest hundred would be 274,389,451,400
Answer:
You make a factor tree for (-)40 where the factors of -40 are -8 and +5. This becomes (x+5)(x-8) which can be multiplied to get back to the starting point.
X^2 + y^2 = 81 is the equation of a circle you specified
