What is (3a-b)+2a equal to?

zaharov [31]

You have to combine like terms, so 3b plus 2b equals 5b and you can't add b to 5a because they aren't defined, therefore th answer is 5a+b.

Use the diagram to answer the questions

IRISSAK [1]

Answer:

1. B. BD

2. C. 15

3. A. 2

Step-by-step explanation:

1. From the figure,

∠DAB = ∠DAC

Therefore, BD is the bisector of ∠ABC.

2. From the figure, IG = GH

3x = 5x - 10

10 = 5x - 3x

2x = 10

x = 5

So, GH = 5x - 10

= 5(5) - 10

= 25 - 10

= 15

Therefore, GH = 15.

3. From the figure,

∠DAB = ∠DAC

10y = 8y + 4

10y - 8y = 4

2y = 4

y = 2

A regular polygon inscribed in a circle can be used to derive the formula for the area of a circle. The polygon area can be expr

Marat540 [252]

Answer:

Option (D)

Step-by-step explanation:

Formula to get the area of a regular polygon in a circle will be,

Area = $n[\frac{1}{2}\times (\text{Base})\times (\text{Height})]$

= $n[\frac{1}{2}\times (\text{s})\times (\text{h})]$

Here 'n' is the number of sides.

If n increases, h approaches r so that 'rh' approaches r².

In other words, if the number of sides of the polygon gets increased, area of the polygon approaches the area of the circle.

Therefore, Option (4) will be the answer.
