Answer:

$\huge{ \fbox{ \sf{x = 21}}}$

Option C is correct.

Step-by-step explanation:

$\underline{ \underline{ \mathfrak{Let's \: solve}}} :$

$\bigstar{ \sf{ \: \: x - 4 = 17}}$

$\text{Step \: 1} : \sf{Move \: 4 \: to \: right \: hand \: side \: and \: change \: its \: sign}$

$\longrightarrow{ \sf{x = 17 + 4}}$

$\text{Step \: 2} : \sf{Add \: the \: numbers}$

$\longrightarrow{ \sf{x = 21}}$

The value of x is 21

Hope I helped!

Best regards! :D

A cylinder has a base diameter of 10cm and a height of 14cm. What is its volume in cubic cm, to the nearest tenths place?

Dvinal [7]

Volume of any cylinder = π times (radius)² times (height or length)

Radius of your cylinder = 1/2 of the diameter =5 cm

Volume = π (5 cm)² (14 cm) = 350 π cm³ = 1,099.56 cm³ (rounded)

A perpendicular bisector is a straight line drawn at an angle $90^{o}$ to a given line segment and divides the segment into two equal parts. Thus the appropriate answer to the question is option B. Definition of the perpendicular bisector.

A bisector is a line that divides a given line segment into two equal parts. It is always drawn at a right angle to the given line segment, thus sometimes referred to as a perpendicular bisector.

So in the given question, line CD divides AB into two equal halves and it is drawn at an angle of $90^{o}$ .

Such that;

<AED = <BED (right angle property)

Therefore, segment CD is a perpendicular bisector of segment AB.

Thus the required answer is option B. Definition of the perpendicular bisector.
