Emilia: y = 60 - 2 x
William can pack 15 toys per hour
Answer: 1.5x
Step-by-step explanation:
If the figure dilates by 1.5 times it will increasingly do the same with the perimeter. It keeps the same ratio of 1.5x.
Ex: If a side of the figure was originally 10 and the dilation factor is 1.5 the side now with be 15. This goes for all sides.
Hope this helps!
The roots of this equation are x = -5.5 and x = -.5
We can find this by using the quadratic equation which is listed below.

Now in order to find the right numbers to put into this equation. we look back to the original problem. Our a value will always be the number attached to x^2 (in this case 4), the b value will be attached to x (24) and the c value will be attached to no variable (11). Now we can do the operations and solve.



-3 +/- 5/2
-3 + 5/2 = -0.5 and -3 - 5/2 = -5.5
Giving you those x values.
