Answer: D.
Step-by-step explanation:
Factors of 8 are: 1 and 8, 2 and 4
Factors of 9 are: 1 and 9 and 3 (3x3=9)
Factors of 10 are: 1 and 10, 2 and 5
Factors of 11 are just 1 and 11
Sure,I do not agree because the answer is -20>-27
AX = B
1 -1 -1 x 0
0 -2 -1 y = -2
2 1 0 z -4
x
y = A^-1 B
z
x -1 1 1 0 6
y = 2 -2 -1 . 2 = -8
z -4 3 2 4 14
Answer:
r = 8
Step-by-step explanation:
59 = 7r + 3
Switch sides:
7r + 3 = 59
Subtract 3 from both sides:
7r = 56
Divide both sides by 7:
r = 8
