Answer:
13.5
Step-by-step explanation:
(Are you meaning this as the answer is a decimal?)
3/50 * 225/1
<em>Cross-cancel 50 and 225 by cancelling out 25.</em>
3/2 * 9/1
<em>Rewrite this so it is a single fraction.</em>
(3 * 9)/2
<em>Multiply 3 by 9 to get 27.</em>
27/2
<em>Divide 27 by 2 to get 13.5.</em>
13.5
6% of 225 is 13.5.

7x + x + 20 = 180
8x = 160
x = 20
You forgot to post the picture of the graph
(3x+2)(x-7)
All you need to do is FOIL.
3x^2-7x+2x-14
3x^2-5x-14
