The answer is going to be x=5
Answer:
Number of steps = 10,560 steps
Step-by-step explanation:
Number of steps : number of miles = 3168 : 1.5
how many steps will he need to walk 5 miles?
Let number of steps = x
Number of steps : number of miles = x : 5
3168 : 1.5 = x : 5
3168/1.5 = x/5
Cross product
3168 * 5 = 1.5 * x
15,840 = 1.5x
x = 15,840 / 1.5
= 10,560 steps
x = 10,560 steps
Number of steps = 10,560 steps
The right answer for the question that is being asked and shown above is that: In the function f(x) = 4(x2 − 6x + ____) + 20, what number belongs in the blank to complete the square?
x2 - 6x + 9
So the answer on the blank space is 9. It should be a perfect square.
= 6/2
= 3^2
= 9
