Answer:
-16t²+17t+7=11
==>16t²-17t+4=0
Δ=17²-4*4*16=33
==>t= (17-√33)/32=0.351732... (s)≈0.35 (s)
or t=(17+√33)/32=0.710767 (s)≈0.71 (s)

It would be y=-7x-6 if it where parallel, and it would be y=7x-6
The result of the product of the sides of the triangles is 9
<h3>Shapes and Patterns</h3>
From the given diagram, you can see that the triangle and the shape circumscribed around it forms patterns given as:
- Product = sides of the triangle * number of sides of the circumscribed shape
For the circle and triangle
Product = 0 * 3
Product = 0
For the rectangle and triangle;
Product = 3 * 4
Product = 12
For the two triangles
Product = 3 * 3
Product = 9
Hence the result of the product of the sides of the triangles is 9
