Polygon C CC has an area of 40 4040 square units. Kennan drew a scaled version of Polygon C CC using a scale factor of 1 2 2 1

xenn [34]

Answer:

10 square units.

Step-by-step explanation:

Area of Polygon C = 40 square units.

Scale factor used in obtaining polygon D = $\dfrac12$

To obtain the area of the new polygon, we multiply the area of the polygon from which it was derived by the square of the scale factor.

Therefore:

Area of Polygon D

$=40 \times (\frac12)^2\\\\=40 \times \frac14\\\\=10$ square units$

The area of polygon D is 10 square units.

What is the following product?<br> 3v2(5v6-7v3)

steposvetlana [31]

Answer:

$3v^2\left(5v^6-7v^3\right)=15v^8-21v^5$

Step-by-step explanation:

Given the expression

$3v^2\left(5v^6-7v^3\right)$

Apply the distributive law

$a\left(b-c\right)=ab-ac$

$a=3v^2,\:b=5v^6,\:c=7v^3$

$=3v^2\cdot \:5v^6-3v^2\cdot \:7v^3$

$=3\cdot \:5v^6v^2-3\cdot \:7v^3v^2$

$=15v^8-21v^5$

Thus, we conclude that

$3v^2\left(5v^6-7v^3\right)=15v^8-21v^5$
