Here's [10] if you don't beat me to it by the time I finish typing:

= 9t^2 + 6t + 6t + 4
= 9t^2 + 12t + 4

ANSWER: (3t + 2)(3t + 2)

Percentage decrease = (3.7 - 5.6)/5.6 * 100%

= -1.9/5.6 * 100% = -33.93%

How do you solve with all the steps?<br> |-2(x+2)|=1
Tanya [424]

Answer:

x = - 5/2 or x = - 3/2

Step-by-step explanation:

|-2(x+2|=1

|-2x-4|=1
