Answer:
-9
Step-by-step explanation:
x² -16 = (x -4)(x +4)
This magnitude of this product can only be prime if one of the factors is ±1. Any other integer value of x will produce a composite number (or zero).
... For x-4 = ±1, x = 3 or 5
... For x+4 = ±1, x = -3 or -5
The values of x that are ±3 both give |x²-16| = 7, a prime.
The values of x that are ±5 both give |x²-16| = 9, not a prime.
The two values of x that are of interest are x=-3 and x=3. Their product is ...
... (-3)·(3) = -9
Answer:
The surface area of cone = 54π cm²
Step-by-step explanation:
Given ;
Radius = 3 cm
slant height = 15cm
The surface area of cone = πr ( r + l )
=> π × 3 ( 3 + 15)
=> π × 3 ( 18)
=> 54 π cm²
F(3) = 2(3)+6
f(3)= 6+6
f(3)=12
Hope this helps!
To find that , divide the estimate by the actual weight and multiply by 100.
8/6*100=133.33%(rounded)
Therefore the percent error is 133.33%.
<u><em>Column B i the nearest one.</em></u>
<u><em>2.011 rounded to the nearest is 1. 1 is on Column B.</em></u>
<u><em>So B is the answer.</em></u>
<u><em>Hope you get good marks and good luck!</em></u>
