Answer:
r= 15
Step-by-step explanation:
When you make the product of a binomial of the kind x + a times other binomial that is of the kind x - a, you obtain another binomial (not a trinomial), so any example with that form will be a counterexample that disproves the conjecture:
(x + a) * (x - a) = x^2 - a^2
For example, (x +3) * (x - 3) = x^2 - 9. So, not always the product of two binomials is a trinomial.
The distance of the plane flies between the two cities is 1,113.75 miles
The formula for calculating the distance travelled is expressed as:
D = vt where:
v is the speed
t is the time taken
Given the following:
v = 99mi/hr
Total time taken = 5hr + 6.25hr
Total time taken = 11.25hr
Get the required distance
Distance = 99mi/hr * 11.25hr
Distance = 1,113.75miles
Hence the distance of the plane flies between the two cities is 1,113.75 miles
