Part A:
The two expressions are equal because in the second expression all they did was move the decimal over one place to make it so both numbers had the same exponent value.
Part B:
The second expression takes less steps to solve because you can simply subtract the two numbers.
0.14-2.83 = -2.69
-2.69*10^4
Answer:
Step-by-step explanation: I don't
15r means that she burns 15 calories per min, for as many mins as she ran. EG: if she ran for 10 min, then she burned 150 cals. The other one I'm not so sure.
Answer:

Step-by-step explanation:
4x-16=-20
Get x to one side by subtracting it.
-16=-20-4x
Add the 20 on both sides.
-16+20=-4x
Simplify
4=-4x
4/-4=-4x/-4
-1=x
x=-1
Area = \frac{a X p}{2}
Area = apothem times perimeter over 2
