Answer:4:28
Step-by-step explanation:because you multiply the left and right hand by 4 and u get 4:28 which adds up to 32
200 can be rounded down to 200, which is easy to add with. Thus, an estimate is 222+200=422.
Alternatively, you could round 222 up a bit, to get 225+200=425. This is actually the correct answer, but this rounding doesn't make the calculation easier, so if you needed a quick estimate I'd go with the first option.
9x^4 -225y^8
= 9(x^4 - 25y^8)
= 9(x^2 + 5y^4)(x^2 - 5y^4)
10C = 80, solve for C by dividing both sides by 10. C = 8
