Answer:AE=EC và BF=FC => EF là đường trung bình của tam giác ABC
=> EF // và bằng 1/2 AB
=> AB = 16
Step-by-step explanation:
The number of hours Nick took to reach the shopping mall in terms of r is ; 3.14 hours.
<h3>What is rate?</h3>
Rate is a measure of a quantity using another quantity as the basis.
Analysis:
speed travelling on foot = r
distance travelled on foot = 5 miles
time taken = 5/r
speed travelling on bicycle 80 percent faster than on foot is 1.8r
distance travelled on bicycle = 8 miles
time taken = 8/1.8r = 40/9r
total time taken to get to the mall = 5/r + 40/9r = 85/9r
speed while walking = 3 miles per hour = r
time taken = 85/9 x 3 = 3.14 hours
In conclusion, number of hours Nick took to reach the shopping mall in terms of r is 85/9r is 3.14 hours.

Answer:
The correct options are,
x = -2 and x = 3
Step-by-step explanation:
It is given that,
x² - x - 6 = 0
<u>To find the solution of given equation</u>
x² - x - 6 = 0 can be written as
x² + 2x - 3x - 6 = 0
x(x + 2) - 3( x + 2) = =
(x + 2)(x - 3) = 0
Either (x + 2) = 0 or (x - 3) = 0
If (x + 2) = 0 then x = -2
If (x - 3) = 0 then x = 3
Therefore the correct options are,
x = -2 and x = 3
First, solve within the parentheses. 18/6=3. Now solve the multiplication and division 1/2x6=3. The equation is now 3+9-3. Add and/or subtract from left to right. 3+9=12. 12-3=9. The answer is 9.
Hello
It is a visual thing. You can see how big or small the fraction is. So the one that is shaded the most in the fraction strip will be the largest fraction, and the one that is shaded the least is the smallest fraction.
Have a nice day
