The best step to do next is to add 80 to both sides of equation:
5 ( x² + 8 x ) + 80 = 14 + 80
and since 80 = 5 · 16
5 ( x² + 8 x + 16 ) = 94 Answer : B )
After that we will continue like this:
5 ( x + 4 )² = 94
( x + 4 )² = 18.8 ... etc
Answer:
78°
Step-by-step explanation:
when two lines intersect it creates 4 seperate angles, here it gives us 78°, and we know that the angle across from it is the same, so they equal.
The z-score of 30,000 is -2. Reference to a normal standard distribution table shows that 97.72% of tires will have a life of at least 30,000 miles.
<span>The length (L) is directly proportional to the square of the time period (T) =>
L = K * T^2
That is a quadratic relation.
