Answer:

The area of the regular polygon is 17.5.

Step-by-step explanation:

To find the area of the regular polygon with a perimeter of 14 and radius of 2.5, the following calculation must be performed, knowing that the area of a regular polygon arises from multiplying the perimeter by the apothem divided by two:

(14 x 2.5) / 2 = X

35/2 = X

17.5 = X

Therefore, the area of the regular polygon is 17.5.

What is the value of x in the equation 3x-4y=65, when y equals 4?

andreev551 [17]

Answer:

x = 27

Step-by-step explanation:

3x - 4y = 65

3x = 65 + 4y

Find x, when y = 4

3x = 65 + 4 (4)

3x = 65 + 16

3x = 81

x = 27 $[ \ x = \frac{81}{3}\ ]$

2x2 + 24x + 72 = 0 options: {−6} {−6,0} {−9,−6, 0} {−9,−4}

kodGreya [7K]

Answer:

x = -6

Step-by-step explanation:

Solve for x over the real numbers:

2 x^2 + 24 x + 72 = 0

Divide both sides by 2:

x^2 + 12 x + 36 = 0

Write the left hand side as a square:

(x + 6)^2 = 0

Take the square root of both sides:

x + 6 = 0

Subtract 6 from both sides:

Answer: x = -6

Four points which lie at (0,0) ; (0,2) ; (2,2) ; (2,0)

$\large \green{ \underline{ \blue{ \boxed{\bf{ \red{To \: Find-}}}}}}$

What is the figure formed?What is the area of the figure?

$\large \green{ \underline{ \blue{ \boxed{\bf{ \red{Solution-}}}}}}$

The given points lie on graph as per the order given in the attachment.

Which shape?

As the points lie 2 units apart from their adjacent sides. It can be a square or rhombus.

The opposite pairs of sides are also parallel to each other. The adjacent sides of the figure formed are also perpendicular to each other.

Hence! the figure formed is a square.

What is the area?

$\large{\sf{ \longmapsto Area_{(square)} = s \times s}}$

$\large{\sf{ \longmapsto Area_{(square)} = {s}^{2} }}$

$\large{\sf{ \longmapsto Area_{(square)} = {(2)}^{2} }}$

$\large{\sf{ \longmapsto Area_{(square)} = 4 \: sq. \: units}}$
