Point D is the centroid of Triangle ABC. Find CD and CE.<br> DE = 9
sukhopar [10]

Given:

Point D is the centroid of Triangle ABC and DE = 9.

To find:

The measures of CD and CE.

Solution:

We know that, centroid is the intersection of medians and it divides each median in 2:1.

In triangle ABC, CE is a meaning and centroid D divided CE in 2:1. So,

Let the measures of CD and DE are 2x and x respectively.

DE = 9                (Given)

x=9

Now,

CD=2x

CD=2(9)

CD=18

And,

CE=CD+DE

CE=18+9

CE=27

Therefore, the measure of CD is 18 units and the measure of CE is 27 units.

Which inequality is equivalent to I x-4 I &lt;9
Leni [432]

(B) –9 < x – 4 < 9 inequality is equivalent to Ix-4I <9.

<h3>What is inequality?</h3>
  • Inequality is a statement of an order relationship between two numbers or algebraic expressions (greater than, greater than, or equal to, less than, or less than or equal to).
  • Inequality is defined as a difference in size, amount, quality, social position, or another factor.
  • Inequality occurs when you have ten of something and someone else has none.
  • (mathematics) A statement stating that one quantity is less than (greater than) another.

So, Ix-4I <9:

  • |x-4|<9 ⇒ -9 < x-4 < 9
  • -5 < x < 13

Therefore, (B) –9 < x – 4 < 9 inequality is equivalent.
