Answer:
parallel
Step-by-step explanation:
they have the same slope, but different y intercepts
The correct next step Amy could take is to factor (x^2 - 16) on the left side of the equation to yield (x + 4)(x – 4)(x + 2) = 0.
The equation is given as:

The possible next steps are:
1. Expand the equation as follows

2. Express x^2 -16 as a difference of two squares as follows

However, the correct step in this case is to factor x^2 - 16 as a difference of two squares to give 
This is so, because the question says Amy is trying to solve for variable x.
This step will ensure that she gets the possible values of x, unlike expanding the whole equation .
Hence, the correct next step is

Answer:
acute
Step-by-step explanation:
obtuse is over 90°
acute I less that 90°
and right is exactly 90°
Multiple 5x70 to get 350. Which makes the equation 350=5x and then you have to divide both sides by 5 to get x by itself. so 5x/5 and 350/5 makes x=70
Answer:
26.6 miles
Step-by-step explanation:
distance = speed × time ( time is in hours )
= 7.6 × 3.5
= 26.6 miles
