Answer:

one ten was traded for ten ones

Step-by-step explanation:

372 cannot be divided by 3 easily. However, 360 +12 can be divided by 3 easily, so it makes sense to trade one of the seven tens for ten ones. That will leave 6 tens, but give twelve ones.

370 +2 = 360 +12 . . . . where the "+" numbers are the numbers of ones

777dan777 [17]

Answer:

Step-by-step explanation:

The dimensions of the portrait are attached.

The total area of the portrait is represented by its width 5+x and its length x+1.

We know by definition that the area of a rectangle is

$A= w \times l$

Where $w$ is the width and $l$ is the length.

Using the given expressiones, we have

$A=(5+x)(x+1)=5x+5+x^{2} +x=x^{2} +6x+5$

Therefore, the right answer is D.
