Answer: A)
Step-by-step explanation: If You just look at the numbers you can single out which one is correct
Answer: 5 (8-9x)
Step-by-step explanation:
25 x 2 - 45 x -10
50 - 45 x -10
40 - 45x
We know that for √x to be meaningful, we must have x ≥ 0.
If we square both sides of the inequality, we have
x < 4²
x < 16
Thus the whole solution is
0 ≤ x < 16
The following choices are valid solutions to the inequality:
B. 12
C. 2
E. 5
I assume that x = figure no.
It's better to write this as
Tiles = 10n-18
Thus 10(12) - 18
=120 - 18
= 102
THUS HE IS WRONG.
