Answer:

x + 4√(x + 2) + 6

Step-by-step explanation:

All we need to do is expand by using FOIL (First, Outside, Inside, Last):

x + 2 + 2√(x + 2) + 2√(x + 2) + 4

Then we combine like terms to get our final answer:

x + 2 + 4√(x + 2) + 4

x + 4√(x + 2) + 6

Permutations and combination question ^^
mario62 [17]

Answer:  22) A

<u>Step-by-step explanation:</u>

First, order doesn't matter so it is a Combination.

<em>In other words, it doesn't matter which person was chosen 1st, 2nd, 3rd, or 4th to bring food because they are all bringing "food".</em>

Next, If you are going to choose  person to 4 people to bring food out of a total of 4 + 3 + 1 = 8 people, you get → ₈C₄

And you are going to choose 3 people to bring decorations out the remaining 8 - 4 = 4 people, you get → ₄C₃

And you are going to choose 1 person to be the host out of the remaining 4 - 3 = 1 person, you get → ₁C₁

"And" means multiplication so altogether you get ⇒  ₈C₄ × ₄C₃ × ₁C₁

❥

Area of circle is 50.29(≈)cm² and perimeter of circle is 25.14(≈)cm.

❥

•Given :-

Diameter of the circle = 8 cm.

•To find :-

Area and perimeter of the circle.

• Solution :-

Let the radius of the circle be r cm.

Diameter = 8 cm.

We know,

★

So, Radius (r) = 8/2= 4 cm.

We know,

★

Area of circle= πr²

→Area of circle=

→Area of circle=

→Area of circle= 50.29(≈)cm²

A parallelogram has a base of length 2x + 1 and a height of x + 3 and has an area of
storchak [24]

Answer:

  • base 7
  • height 6

Step-by-step explanation:

Using the given expressions, we can write the area as ...

  A = BH

  42 = (2x +1)(x +3) = 2x^2 +7x +3

  2x ^2 +7x -39 = 0

  (x -3)(2x +13) = 0

  x = 3   or   -6.5  . . . . .  these values make the factors be zero

In order for the parallelogram to have positive dimensions, the value of x must be 3. So, the base and height are ...

  base = 2(3) +1 = 7

  height = 3 +3 = 6
