In the diagram, the length of segment BC is 23 units. Line l is a perpendicular bisector of line segment A C. It intersects line segment A C at point B. Line l also contains point D. Line segment A B is 2 x + 7. Line segment A D is 4 x + 1. What is the length of segment DC? 13 units 18 units 33 units 46 units

The length of segment DC is 33 units.

Step-by-step explanation:

A perpendicular bisector of line segment divides the line into two equal parts at 90°.

This implies that the perpendicular bisector of line segment AC at B divides the line Ac into two equal parts AB and BC.

It is given that:

BC = 23 units

AB = 2x + 7 units

AD = 4x + 1 units

The measure of AB is 23 units, according to the perpendicular bisector definition.

Compute the value of x as follows:

AB = 2x + 7

23 = 2x + 7

2x = 23 - 7

2x = 16

x = 8 units

Then the measure of side AD is:

AD = 4x + 1

     = 4 × 8 + 1

     = 32 + 1

     = 33 units

Consider the diagram below.

Consider the right-angled triangle ABD.

Use Pythagoras theorem to compute the length of DB² as follows:

Consider the right angles triangle DBC.

Use Pythagoras theorem to compute the length of DC² as follows:

Thus, the length of segment DC is 33 units.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total
