X + (x+1) =  2x+1
Here, 2x+1 is always odd
  For example the value of x is 2 then we can say that,
x=2; x+1=3; 2x+1 = 5 <u>[odd number(5)]</u>
= 2 + 3 = 5

HOPE IT HELPS!

HELP ME PLEASEEEEEEEEEE
USPshnik [31]

Answer:

The perimeter of rectangle JKLM is 16 units.

Step-by-step explanation:

Perimeter is the area around the shape, so if you look at the space between K and J, the units there are 7. Multiply 7 by 2 (since there are two sides), and then add 2. 2 + 14 = 16.

Select all the ways the rectangle could have been rotated to get from Frame 1 to Frame 2. 40 degrees clockwise 40 degrees counte
Klio2033 [76]

Answer:

40 degrees clockwise

140 degrees counterclockwise

Step-by-step explanation:

The rectangle is rotated in Figure B. The angle of rotation is 40 degrees. If we rotate a rectangle at an angle of 40 degrees clockwise then wit will be at the position as shown in figure B. The 90 degrees angle is perpendicular angle. Rectangle will not reach the desired position. If we rotate the rectangle at 140 degrees counterclockwise this will be the figure B representation. The rotation to 90 degree counterclockwise is either not suitable for the desired rectangle position.

Answer: ∠REA = 53°

Step-by-step explanation:

Since ∠BEA = 71°, set both angle measures equal to that.

2x + 5x + 8 = 71

Solve for x. First, combine like terms:

7x + 8 = 71

Then, subtract 8 from both sides:

7x = 63

Divide both sides by 7:

x = 9

Now, plug x into ∠REA:

∠REA = 5x + 8

∠REA = 5(9) + 8

∠REA = 45 + 8

∠REA = 53°

Hope this helps!

The curved surface area of a right circular cylinder of height14 cm is 88 cm2. Find the diameter of the base of the cylinder.
Svet_ta [14]

Answer:

4

Step-by-step explanation:

The formulae for Curved surface

area = πrh

Area = 88cm2

height = 14cm

radius = ?

Let π be 22/7

88 = 22/7 x r x 14

cross multiply

88 x 7 = 22 x 14 x r

616 = 308r

Divide both sides by 308

r = 2

Diameter = Radius x 2

so our radius is 2, 2 x 2 = 4
