Step-by-step explanation:
9 + x = 17
17 - 9 = x
x = 8
9514 1404 393
Answer:
80

ab is the product of 'a' and 'b'. For the given values, that is the product ...
ab = (-16)(-5) = 80
_____
When the number of minus signs is even, the resulting product is positive.
Answer:
Absolute value equation is; |x - 25| ≤ 3
Minimum number of bolts is 22 while Maximum number of bolts is 28
Step-by-step explanation:
We are told that;
Each bag should have 25 bolts in it but 22 or 28 is acceptable.
Since 22 or 28 is acceptable, it means the allowable error is ±3.
Thus, if x is the number of bolts in the bag, the absolute value equation would be;
|x - 25| ≤ 3
Minimum number of bolts is 22 while maximum is 28
To find the length of each side 72/4
Each side is 18
So area is 18 times 18= 324
