Answer:
x=4.63
Step-by-step explanation:
Area = (1/2) (base) (height)
20 = (1/2) (x+4) (x)
40 = x²+4x
x²+4x-40=0
Put in quadratic equation:
x=
x=
x=4.63324958071 or x=-8.63324958071
Since x can't be negative in this case we take our answer to be 4.63324958071, which rounds to 4.63
Based on the information given, the speed is 20 miles per hour.
From the information given, the winner of the local triathlon swam 0.5 miles, biked 15 miles and ran 2.5 miles and he finished the race in 54 minutes.

Answer:
(two sixths)
Step-by-step explanation:
if we scale the fraction 1 / 3 to find equivalent fractions, we can simply multiply both numbers by the same factor.
So, by multiplying both 1 and 3 by two, we will have an equivalent fraction
1 × 2 = 2
_ _
3 × 2 = 6
This means that
(one third) is equivalent to (two sixths)
