X cannot be negative, so the first option and the third option are out.
when x = 1, f(x) = -1; when x = 4, f(x) = -2 and when x = 9, f(x) = -3. Hence the last option.
Answer:
x= -22
Step-by-step explanation:
(x-6)/4=-7
-22-6 / 4 = - 7
Squares of Natural numbers from the range of 1 to 20:
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
(whereas 5^2 = 25 which is outside the range).
There are 4 numbers out of 20, so the probability is 4/20*100% = 20%

Answer:
D
Step-by-step explanation:
The opposite faces are congruent, that is the surface area (SA) is
SA = top/ bottom + 2 sides + front/ back
= (3 × 2) + (3 × 2) + (2 × 5) + (2 × 5)+ (3 × 5) + (3 × 5)
= 6 + 6 + 10 + 10 + 15 + 15
