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:
4 + (2 + 1)2 = 4 + (3)2 = 4 + 9 = 13
2/5x - 1 = 9
+1 +1
10

2/5 2/5
x = 50
The thing that's wrong with the equation is that 2 shouldn't be multiplied by 4 but should have been added.
<h3>How to illustrate the information?</h3>
From the information given, it can be seen that the equation is:
(3x²)(-2x⁴) = 3(-2)x² × x⁴ = 6x^8
Based on the information above, this calculation is incorrect. The correct calculation will be:
(3x²)(-2x⁴) = 3(-2)x² × x⁴
= -6x^6
Therefore, the multiplication should be an addition of the power.
