The answer is D. 25
It’s easiest to find the solution by drawing out the triangles side by side with the lengths. It is what I did to find the answer
Answer:
(A U B U C)={ 3,6,8,9,12,13,14,15,16,18,21,23,24,25,26,30}
(A n B n C) = {14,15}
Step-by-step explanation:
Union of sets is the combination of all the values in the given set into one set
Intersection of sets is the combination of all the common terms in each set into one set.
<h2>THREE</h2><h2></h2><h3>Solved in two seconds.</h3><h3>22 - 10 = 12</h3><h3>12 ÷ 4 = 3</h3><h3>Literally just reversed it.</h3>
Let the two consecutive even integers be x and x+2.
Then x^2 = (x+2) + 10
Simplifying, x^2-x -2 - 10 = 0, or x^2 - x - 12 = 0. Factoring,
(x-4)(x+3) = 0. Solving for x: x=4 and x= -3.
If the first number is x = 4, then the second is x+2=4+2=6.
But wait! If the first number is -3, then the second is x+2 = -3+2 = -1.
