Answer:
The function of f(x) is 20 for the middle problem idk the others
Step-by-step explanation:
To find the mean, add all the numbers then divide by the amount of numbers there are to find the average.
210+160+200=570
570÷3=190
Answer: 190
Answer:
121°
Step-by-step explanation:
<B = 9x - 5°
<D = 10x - 19°
<B = <D ( being opposite angles of parallelogram)
9x - 5° = 10x - 19°
10x - 9x = 19° - 5°
x = 14°
Now
<B = 9x - 5°
= 9 * 14° - 5
= 121°
Answer:
i believe the answer would be 6
Step-by-step explanation:
Volume = w * h * l
w = w, h = 12, l = w + 3
1,560 = w * 12 * w + 3
1,560 = 12w^2 + 3
-12w^2 = 3 - 1,560
-12w^2 = -1557
w^2 = 519/4
w = 11.39079 cm
You can round it if you want
