Answer : D

$\frac{3t^2-4t+1}{t+3} - \frac{t^2+2t+2}{t+3}$

The denominators are same

So we combine the numerators

$\frac{(3t^2-4t+1)-(t^2+2t+2)}{t+3}$

To remove parenthesis we distribute negative sign inside the second parenthesis

$\frac{3t^2-4t+1-t^2-2t-2)}{t+3}$

$\frac{2t^2-6t-1)}{t+3}$

Morgan made a mistake. He forgot to distribute the negative sign

Morgan forgot to distribute the negative sign to two of the terms 2t and 2 inside second parenthesis

49 square units

Step-by-step explanation:

When the length of the sides of a figure are increased by a scale factor, the area is increased by the square of that scale factor.

Since the scale factor used is 7, this means the area is increased by a factor of 7² = 49.

Multiplying the area of polygon V by the scale factor, we have 1(49) = 49.
