noah and lin use the diagram to find the area of the training center. the diagram shows lengths and widths in meters. noah writes 40(y + 25.5) to find the area. lin writes 40y + 1020 to find the area. who do you think is correct? noah only lin only they are both correct. neither of them is correct.

Answer

Explanation:

Step1: Aplicar la propiedad distributiva

Usando la propiedad distributiva $a(b + c)=ab+ac$, donde $a = 40$, $b=y$ y $c = 25.5$. Entonces $40(y + 25.5)=40\times y+40\times25.5$.

Step2: Calcular el producto

$40\times25.5 = 1020$, así que $40(y + 25.5)=40y+1020$.

Answer:

C. They are both correct.
