Answer:
4) 2xy(x^2-2x-8) 2xy(x-4) (x+2)
5) 3(x^2-9x-10 3(x+1) (x-10)
Step-by-step explanation:
Remember
|a|≥0 for all real values of a
so
|x-2|+4≤3
minus 4 both sides
|x-2|≤-1
false, absolute value can never be negative
no solution
a is answer
Answer:
Please fins attached the required labelled drawing
Step-by-step explanation:
The given parameters are;
1) Lines AB and m are both coplanar on plane S and are perpendicular to each other intersecting at point B
2) Plane R and plane S intersect on line p
3) Line AB and line p are perpendicular to each other and both intersect with line n at point A
Answer:
B. 97.2
Step-by-step explanation:
The sequence of positive terms is ...
54, 24, 10 2/3, 4 20/27, ...
This sequence has first term 54 and common ratio 24/54 = 4/9. The sum of the infinite series is ...
S = a1/(1 -r) = 54/(1 -4/9) = 54(9/5)
S = 97.2
The sum of the positive terms in the infinite series is 97.2.
