The first step for solving this expression is to remove the first set of parenthesis.
8j³ - 10j² - 7 - (6j³ - 10j² - j + 12)
When there is a "-" sign in front of the parenthesis,, you must change the sign of each term in the parenthesis. This will look like the following:
8j³ - 10j² - 7 - 6j³ + 10j² + j - 12
Eliminate the opposites in the expression
8j³ - 7 - 6j³ + j - 12
Collect the first set of like term (ones with j³)
2j³ - 7 + j - 12
Calculate the difference between basic numbers
2j³ - 19 + j
Lastly,, use the commutative property to reorder the terms
2j³ + j - 19
Since you cannot simplify this expression any further,, the correct answer to your question is 2j³ + j - 19.

Answer:
Q = 3
Step-by-step explanation:
3 * P + 7 * Q + 15 * R = 102
7Q = 102 - 3P - 15R
Q = (102 - 3P - 15R)/7
Try P = 2; R = 3
Q = 51/7 not an integer
Try P = 2; R = 5
Q = 21/7 = 3
Solution: P = 2; Q = 3; R = 5
Answer: Q = 3

Step-by-step explanation:
Answer:
96 units squared
Step-by-step explanation:
The surface area of a cube can be written as 6 * (s^2)
s is the side length.
4^2 = 16.
6 * 16 = 96.
This is because the area of a cube is s^2.
There are 6 sides to a cube, so we multiply them.
