The dimensions of a 3-ft by 6-ft rectangle are multiplied by 1/3. How is the area affected?

1 answer:

3 0

The area will be 1/9 times the area of the normal dimension. Furthermore,
Area of the dimension:
3×6=18 square feet
Area of the scale drawing;
(3×1/3)(6×1/3)=2. Now, we see that the area of the scale drawing is 2/18 or 1/9 times the area of the normal dimension. Hope it help!

Which equation is an identity?

zloy xaker [14]

3w + 8 - w = 4w - 2(w - 4)
is an identity
3w-w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
2w - 2w = 8 - 8
0 = 0
zero equal to zero implies that any value of w satisfies the statement 3w + 8 - w = 4w - 2(w - 4) hence it is an identity.
