Answer:
at x = 10, 
Step-by-step explanation:
The given equation is 
Here, lets substitute the value of x = 10
So, the equation simplifies to ,

= (4 x 100) + 170 + 2 = 400 + 170 + 2
= 572
So, at x = 10,
Answer:80 meters
Step-by-step explanation: 24 meters = 36 secs
2 mins = 120 secs
Cross multiply
24×120/36
= 80 meters

<span>The expression given (27x^2)z/(-3x^2)(z^6), can be simplify as below:
By properties of powers, if you have the same base, you can substract the exponents. Then:
=(</span>27x^2)z/(-3x^2)(z^6)
=-9z/z^6 (As you can see: x^2-2= x^0=1)
=-9/z^5 (Then, z^6-1=z^5)
<span>
Therefore, the answer is: The exponent on the variable z is 5.</span>
