Point Q is -6 from point R
Point R is 7 from point T
Point T is -3 from point S
Area = 1/2(6+9)(7)
Area = 1/2 (15)(7)
Area = 52.5 square units
The answer is C. Once you add the like terms x^2 and 4x^2 you get your answer.
Answer:
The number of faces is 29
Step-by-step explanation:
we know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
![V- E + F = 2](https://tex.z-dn.net/?f=V-%20E%20%2B%20F%20%3D%202)
In this problem we have
![V=16](https://tex.z-dn.net/?f=V%3D16)
![E=43](https://tex.z-dn.net/?f=E%3D43)
Substitute in the formula and solve for F
![16- 43 + F = 2](https://tex.z-dn.net/?f=16-%2043%20%2B%20F%20%3D%202)
![-27 + F = 2](https://tex.z-dn.net/?f=-27%20%2B%20F%20%3D%202)
![F = 2+27](https://tex.z-dn.net/?f=%20F%20%3D%202%2B27)
![F = 29](https://tex.z-dn.net/?f=%20F%20%3D%2029)
