Responder:
152 capacetes
Explicação passo a passo:
Dado que:
Número de capacetes = 171
Fração com defeito = 1/9
Portanto, número de capacetes com defeito:
1/9 * 171 = 19 capacetes
Número de capacetes sem defeitos:
Número total de capacetes - número de capacetes defeituosos
171 - 19 = 152 capacetes
By the confront theorem we know that the limit only exists if both lateral limits are equal
In this case they aren't so we don't have limit for x approaching 2, but we can find their laterals.
Approaching 2 by the left we have it on the 5 line so this limit is 5
Approaching 2 by the right we have it on the -3 line so this limit is -3
Think: it's approaching x = 2 BUT IT'S NOT 2, and we only have a different value for x = 2 which is 1, but when it's approach by the left we have the values in the 5 line and by the right in the -3 line.
You will have it in 15 days. Both 5 and 3 have a least common multiple of 15.
Answer(there are assumptions for this answer that you need to confirm and look at):

Answer if the operation is multiplication:
If you meant a closed dot which is the symbol for multiplication.
Answer if the operation is composition:
If you meant an open dot which is the symbol for composition.
Note: I don't know if you actually meant or if 
. Please let me know one way or the other.
Step-by-step explanation:
If we assume the functions are:
since multiplication is commutative.
We are asked to find 
and 
.
The order doesn't matter in multiplication.
Now you might have meant composition which symbolized with an open circle, not a closed one.

Answer:
<h2>204 units²</h2>
Step-by-step explanation:
It's a rectangle. Therefore the opposite sides are congruent.
We have the equation:
2x + 4 = 12 <em>subtract 4 from both sides</em>
2x = 8 <em>divide both sides by 2</em>
x = 4
Put the value of x to the expression 4x + 1:
4(4) + 1 = 16 + 1 = 17
Therefore we have the rectangle with dimesions 17 × 12.
The area of the rectangle:
A = (17)(12) = 204
