KonstantinChe [14]

Answer:

Yes , i agree with Noah that the equation would be 3(x + 7) = 57

Step-by-step explanation:

P.S - The exact question is -

To find  - Noah writes the equation 3 (x+7)=57 to represent the situation.

               DO YOU agree with him? Explain your answer.

Proof -

Yes , i agree with Noah

Because in the figure we can see that there is x written 3 times and 7 written 3 time and whole the values is equal to 57 .

Because 57 is divided into x 7 x 7 x 7

∴ we can write it as

3 times x + 3 times 7 = 57

⇒3(x) + 3(7) = 57

⇒3(x+7) = 57

Ans Noah give the same equation 3 (x+7)=57

So, I agree with Noah.

\bf V=3354~in^3\qquad \qquad 3354=6(w-12)(w+18)&#10;\\\\\\&#10;\cfrac{3354}{6}=w^2+6w-216\implies 559=w^2+6w-216&#10;\\\\\\&#10;0=w^2+6w-775\implies 0=(w+31)(w-25)\implies w=&#10;\begin{cases}&#10;-31\\&#10;\boxed{25}&#10;\end{cases}


since the width is just a dimension unit, it can't be -31.

what is the length?  well, the length is w + 30.
