Respuesta :
The steps in Mia's method were smaller than in Jenna's, which was an advantage.
What is distributive property and direct calculation?
The same result will be obtained by adding the products of multiplying the sum of two or more addends by a number as opposed to multiplying each addend separately by the number.
The direct algorithm process suggested in this paper is known as the direct calculation method (DCM), and it can deal with using confinement loss as an incremental step to simulate the effect of moving tunnel face excavation, calculating the stresses and displacements in each step, and drawing the results.
Jenna's technique:
[tex]\begin{aligned}&5(30+4) \\&=(5)(30)+(5)(4) \\&=150+20 \\&=170\end{aligned}[/tex]
Mia's technique:
[tex]\begin{aligned}&5(30+4) \\&=(5)(34) \\&=170\end{aligned}[/tex]
Find: What was the benefit of using one method over the other and why did Jenna and Mia arrive at the same conclusion?
Future:
Both used the right approach, albeit in different ways.
One uses the distributive property, whereas the other uses direct calculation.
Consequently, Jenna and Mia came to the same conclusion.
However, Mia's approach has one advantage over Jenna's: it requires fewer steps.
