The area of a triangle is always:
A=bh/2  (base times the height divided by 2)
A=3x(2x)/2
A=6x^2/2
A=3x^2
...

To solve for how many miles Rachel jogged if she jogged a 1/4 mile trail 8 times, we simply need to multiply the distance she ran each time by the amount of times she ran it.
1/4 * 8 = 2
Rachel jogged 2 miles.
Hope that helped =)
        
             
        
        
        
Answer:
x = 3
Step-by-step explanation:
4(2-x)+13=2x+3
distribute the 4.
8 - 4x + 13 = 2x + 3
combine like terms.
21 - 4x = 2x + 3
18 = 6x
divide by 6.
x = 3
check.
4(2 - 3) + 13 = 2(3) + 3
4(-1) + 13 = 6 + 3
-4 + 13 = 9
9 = 9
correct!
