Divide 754 by 13 and you get 58
Now multiply by 9 and you get 522 miles.
x = the unknown number
nine <u>times</u>(multiplication) a number(x) divided(division) by 2 equals(=) 54,
so 9x is divided by 2
Let u = x², then we would have u² + 5u - 6 = 0
From here, we can factor it and get us (u-1)(u+6) = 0
So our solution for u is u = -6 or 1.
Now substitute u back to x².
x² = -6 or 1
x = ±√(-6) or ±√1
Since ±√(-6) is not real number, we ignore it.
Which leave us x = ±√1 = <span>±1
So our real solution is x = -1 or 1.</span>
Answer:
Step-by-step explanation:
SA= 2*r*r*pi + 2*pi*r*h
= 2*6*6*3.14 + 2*3.14*6*8
Not an answer, but we need the info on the table...
