U^2 + 2 (u) (5/2) + 25/4 = (u +5/2)^2
answer is B. 25/4
15 miles per hour is the answer because 2/1/2 divided by 1/6 is 15
The number of terms in the expression given is; 2.
<h3>How many term are in the expression given?</h3>
It follows from the task content that the expression given is; (3x^2-3)(3x^2+3).

Answer:

Step-by-step explanation:
Let
y ----> the distance in miles
x ----> the time in hours
using proportion

Simplify


This is a linear direct variation
The unit rate or speed is the slope of the linear equation
The unit rate is 4 miles/hour
(c/ b * 0) is just (c/0) and you cannot divide by 0
