Answer:
a^8 - 12a^4 + 36
= (a^4)^2 - 2*a^4*6 + 6^2
= (a^4 - 6)^2

Answer:
Percent 250 of 275 is 90.9%
Step-by-step explanation:
We have to find 250 is what percent of 275.
Let X be the percentage, then
=> X = 
Now simplyfying the above relation we get
=> X = 
=> => X = 90.9 %
Hence 250 is 90.9% of 275
Step-by-step explanation:
Part A: We can write 40 + x + 25 = 180 because these angles are supplementary, meaning they add up to 180 degrees, and when we solve for x, we get x = 115°.
Part B: We can write y = x + 25 because these two angles are vertical angles, meaning they are equal and formed from the same lines. We know that x = 115°, so when we plug that in we get y = 140°.
Part C: z = 40° because these two angles are vertical angles. I hope this helps!
