Answer:
This is guess of what the question is asking:
I had got 49x - 21y - 6.
Step-by-step explanation:
7 x 7 is 49 and 7 x 3 is 21.
For T = 89.5 degrees C:
E(t) = 1100(90 - 89.5) + 520(90 - 89.5)^2= 1100(0.5) + 520(0.5)^2= 550 + 130= 680 m
For T = 90 degrees C:
E(t) = 1100(90 - 90) + 520(90 - 90)^2= 0 + 0= 0 m (meaning that boiling point is 90 degrees C at ground level)
Answer: just add 75 and 45 + x and do division for 69 ok but times the 45 with 69 ok good luck
