Answer:
The value of 
is -30.
Step-by-step explanation:
Let 
, we notice that expression is a second order polynomials. We can rearrange the polynomial and use factorization to calculate all roots:
(1)
(2)
(3)
From (3) we find the least root:
![x = \sqrt [3]{\frac{8}{27}}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%20%5B3%5D%7B%5Cfrac%7B8%7D%7B27%7D%7D)
By (2) we have the value of :
Hi! the answer should be 104
----
Formula: h(g(x))
1) First you want to take the -5 and plug that into the given equation for g(x)
• 2(-5)= -10
2) Next you want to take the -10 and plug it into the equation for h(x)
• (-10)²+4= 104
Answer:
6.24 is the answer rounded to the nearest hundreth
Answer:
B. 7 hours
Step-by-step explanation:
The formula for time (in this scenario) is t = d/s.
t - time
d - distance
s - speed
For this problem, d - 385 mi and s - 55 mph. To find the time this trip took, you would solve 385/55=7. In the end, Kelly drove for 7 hrs. Hope this helps!!
