For the first question you multiply 4 by 2x and then -1, getting 8x - 4. 3 multiply by 2x and then +5 gives you 6x + 15. 8x +6x = 14x; -4 + 15 = 11. The answer to the first question would be 14x + 11. 

For the second question:
1. 3
2. 1
3. -1
4. -3
The tenth term. -15

In the diagram triangles ABE and ACD are similar.
jolli1 [7]

Answer:

p = 7.2

q = 6.4

Step-by-step explanation:

if the triangles are similar then the side lengths must be proportional :

AC/BA = CD/BE

9/5 = p/4 cross multiply expressions

5p = 36 divide both sides by 5

p = 7.2

same goes for q

9/5 = (q+8)/8 cross multiply expressions

72 = 5(q+8) divide both sides by 5

14.4 = q+8 subtract 8 from both sides

6.4 = q
