We know that
<span>Monica can walk 3.8 kilometers in 40 minutes
and
</span><span>she can jog twice that distance in the same amount of time
that means
in 40 minutes Monica can jog (3.8 km*2)-----> 7.6 km
1 hour=60 minutes
</span>by proportion<span>
7.6 km/40 minutes=x km/60 minutes
x=7.6*60/40----> x=11.4 km
the answer is
11.4 km</span>
Answer:
Area: 5x + 10
Perimeter: 2x + 14
Step-by-step explanation:
Area = length times width
Perimeter = length (2) + width (2)
<u>Area:</u>
Multiply the length be the width. That gives you 5 (x + 2).
Then use the distributive property to simplify this expression. That gives you 5x + 10.
<u>Perimeter:</u>
Multiply the width by 2. That gives you 10.
Multiply the length by 2. That gives you 2x + 4
Add the 2 together. That gives you 10 + 2x + 4.
Combine all like terms. That gives you 2x + 14.
