Answer:

The argument is valid by the law of syllogism.

Step-by-step explanation:

Syllogisms work exactly like the example in this exercise: they structure is the following

Every time $A$ holds, then $B$ holds as well
$A$ is given
Then $B$ must hold.

So, you're told that whenever a triangle has an obtuse angle, it is called an obtuse triangle.

Then, you're told that triangle ABC has an obtuse angle.

Then, triangle ABC is an obtuse triangle.

Find three consecutive integers such as two times the first integer, plus three times the second integer, minus the third intege

NikAS [45]

The three consecutive integers are 5, 6, and 7.

What are consecutive integers?

Whole numbers that follow one another without a gap are known as consecutive integers. A few examples of consecutive integers are 15, 16, and 17, 1,2 and 3, and so on.

Finding the Consecutive Integers

Let the three consecutive integers be a, a + 1, and a + 2.

These three consecutive integers are to be such that two times the first integer when added to three times the second integer minus the third integer, it is equal to 21.

⇒ 2a + 3(a+1) - (a+2) = 21

2a + 3a + 3 - a -2 = 21

5a - a + 3 - 2 = 21

4a + 1 = 21

4a = 20

a = 20/4

a = 5

∴ a+1 = 5+1

a+1 = 6

And, a+2 = 5 + 2

a +2 =7

Hence, the three consecutive integers come out to be 5, 6, and 7
