Answer:
ttttttttttttttttttttttttttttttttttttttttttt
Step-by-step explanation:
<span> −3|x + 7| = −12
* </span><span> −3(x + 7) = −12
-3x - 21 = -12
-3x = -12 + 21
-3x = 9
x = 9/-3
x = -3
</span>
* −3*[ -(x + 7)] = −12
3x + 21 = -12
3x = -12 -21
3x = -33
x=-33/3
x = -11
answer:
x = -11 and x = -3

What are you trying to figure out? This is new to me XD
√19 = 4.36
√77 = 8.77
So integers between √19 and √77 are 5, 6, 7 and 8. And their sum is
5 + 6 + 7 +8 = <u>26</u>
