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
PLS MARK BRAINLEST
Sorry I know this late, but the answer is 40 MPH, I don't know if this helps! I HOPE SO THO!! <3
The angles remain the same. If you equally increase the lengths of the sides, the interior and exterior angles will not change. Both of them are similar to the original sign.
No because a right triangle always has a right angle
I guess no solution
4x +3 = 4X + 18
4X - 4X = 18 - 3
0 = 15
