Answer:
Look at the picture for the answer :D
Step-by-step explanation:
The x coordinate comes first, then the y.
2 - 2n = 3n + 17 > -2n = 3n + 15 > -5n = 15 > n = -3
Answer:
15y^2 - 21y
Step-by-step explanation:
A = LW
A = (5y - 7)(3y)
A = 15y^2 - 21y
Focus on triangles DFC and DFE:
- They are both right triangles because DF is perpendicular to EC
So, the two triangles are congruent. It follows that CF=FE, and in particular

And since x=3, the length of EF is
