Answer:
C
Step-by-step explanation:
I think that is the answer because 5x5x5=125
Answer:
x = .4384471872, x = 1, x = 4.561552813
Step-by-step explanation:
(x-1) is a root. When you divide it into x³-6x²+7x -2, you are left with x²-5x+2. Use the quadratic equation on that.
(5+/-)/2
So the roots are (5 - )/2, 1, and (5 + )/2
Since the train travels at a rate of 70 miles/hour, the train will take 5 hours to have traveled a total of 350 miles. The missing information in the question you've proposed is the value of "H" or the number of hours (as the unit hours is indicated in the question). This can be determined with the formula <em>Distance = rate X time. </em>350 = 70 X H, in this case. To isolate the variable H, 70 (the rate) divides 350 (the total distance) into 5. 350 ÷ 70 = H. 5 = H, the amount of time spent traveling for 350 miles at a rate of 70 miles/hour.
Step-by-step explanation:
Given
25x² - 30x + 9
= 25x² - (15+ 15)x +9
= 25x² - 15x - 15x + 9
= 5x ( 5x - 3) - 3(5x -3)
= ( 5x - 3)(5x - 3)
= ( 5x - 3)²
Hope it will help :)
Your answer would be 0,6.
- Because if you look at it correctly you see the right is at 0 and the top is at 6
