Step-by-step explanation:
n(A) is the number of elements is A, sometimes written |A|. I count 7. n(A)=7
13 is among the elements of A, so 13 ∈ A is TRUE
26 is among the elements of A, so 26 ∉ A is FALSE
10 isn't in A, so 10 ∉ A is TRUE

Answer:
-x + 1 > 3, and 4x + 6 < -2
Step-by-step explanation:
The inequality reads x < -2, so the arrow follows any values that are less than -2. So we need to simplify each inequality in the following options to see which match x < -2.
-4x+3> -5 simplifies to x < 2 so it's wrong
-2x + 4 > -4 simplifies to x < 4 so it's wrong
-x + 1 > 3 simplifies to x < -2, so it's right
2x + 5 < -3 simplifies to x < -4, so it's wrong
4x+ 6 < -2 simplifies to x < -2, so it's right
Answer:
Below.
Step-by-step explanation:
One example is a square.
Another is a rectangle.
Both of these contain 4 right angles.
To find 33% of 1.45 we have to tranform 33% into decimal of traction
33% is 0.33 or
and multiply if by 1.45
so
0.33*1.45=0.4785
or
1.45*
