Answer: 3j-6k+4
Step-by-step explanation:
First you have to distribute the 3 to the j and the -2k since they are both in the parentheses. So it would look like (3*j) +(-2k*3)+4 and if you simplify that it is 3j-2k+4. After that there are no like terms so that is your answer.

The answer to question 5 is D.5 and the answer to question 9 is (-2,-6)
Answer:
(2x + 3)(x - 2)
Step-by-step explanation:
use FOIL
First, Outside, Inside, Last
2x x x = 2x²
2x x -2 = -4x
3 x x = 3x
3 x -2 = -6
2x² - 4x + 3x - 6
Triangle=1/2 times base times height
base=32
height=24
the lateral surface area is not including bottom so just the 4 side triangles
4 times 1/2 times base times height
4 times 1/2 times 32 times 24
2 times 32 times 24
1536
lateral surface area is 1536 square centimeters
