False when you multiply numbers you add the exponents.
Answer:
![2t^3+15t^2+19t+6](https://tex.z-dn.net/?f=2t%5E3%2B15t%5E2%2B19t%2B6)
Step-by-step explanation:
Height of the Rectangle![=t^2+7t+6](https://tex.z-dn.net/?f=%3Dt%5E2%2B7t%2B6)
Width of the Rectangle![=2t+1](https://tex.z-dn.net/?f=%3D2t%2B1)
Area of the Rectangle = Height X Width
![=(2t+1)(t^2+7t+6)\\=2t(t^2+7t+6)+1(t^2+7t+6)\\=2t^3+14t^2+12t+t^2+7t+6\\$Collect like terms\\=2t^3+14t^2+t^2+12t+7t+6\\Area=2t^3+15t^2+19t+6\\](https://tex.z-dn.net/?f=%3D%282t%2B1%29%28t%5E2%2B7t%2B6%29%5C%5C%3D2t%28t%5E2%2B7t%2B6%29%2B1%28t%5E2%2B7t%2B6%29%5C%5C%3D2t%5E3%2B14t%5E2%2B12t%2Bt%5E2%2B7t%2B6%5C%5C%24Collect%20like%20terms%5C%5C%3D2t%5E3%2B14t%5E2%2Bt%5E2%2B12t%2B7t%2B6%5C%5CArea%3D2t%5E3%2B15t%5E2%2B19t%2B6%5C%5C)
The area of the rectangle is ![2t^3+15t^2+19t+6](https://tex.z-dn.net/?f=2t%5E3%2B15t%5E2%2B19t%2B6)

Answer:
C) 14 cm
Step-by-step explanation:
A triangle solver can quickly show you the third side is 14 cm.
__
The law of cosines can be used for this purpose. If the given sides are 'a' and 'b', and the third side is 'c', then that law tells you ...
c² = a² +b² -2ab·cos(C)
c² = 7² +11² -2·7·11·cos(100°) ≈ 196.74
c ≈ √196.74 ≈ 14.03
The length of the third side is about 14 cm.
