Which point of concurrency is NOT always inside a triangle? Check all that apply. A. circumcenter B. incenter C. orthocenter D.
timama [110]

Answer:

Option A. is correct

Step-by-step explanation:

The circumcenter is a point of intersection of all the perpendicular bisectors of a triangle.

The incenter is a point of intersection of all the angle bisectors of a triangle.

The orthocenter is a point of intersection of all the altitudes of a triangle.

The centroid is a point of intersection of all the medians of a triangle.

The incenter, orthocenter, and centroid always lie inside a triangle.

However, a circumcenter does not always lie inside a triangle.

In an acute-angled triangle, the circumcenter may lie inside or outside the triangle.

So,

Option A. is correct

Can someone write out the steps so I understand? <br> 14 + 18 ÷ 2 x 18 - 7
Lina20 [59]

To solve use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

REMEMBER: IF A STEP IS NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .

14 + 18 ÷ 2 x 18 - 7

Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right. In this case that would be division first then multiplication.

NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression

Division

14 + 18 ÷ 2 x 18 - 7

18 ÷ 2 = 9

14 + 9 × 18 - 7

Multiplication

14 + 9 × 18 - 7

9 × 18 = 162

14 + 162 - 7

Addition

14 + 162 - 7

14 + 162 = 176

Subtraction

176 - 7

= 169

Hope this helped!
