Answer:

The answer is B .

Step-by-step explanation

Firstly

   =  (8 - √2 )  × ( 9 + √5 )     (writing the given only )

   =  8 ( 9 + √5)   - √2 ( 9+√5 ) ( multiplying them )

    =  72  +  8√5  - 9√2 -  √10

 Hope you got it now

How would I graph this?
elena55 [62]

y\leq 2x-5

↝ x-intercept

2x-5=0\\2x=5\\x=\frac{5}{2}

↝ y-intercept

y = -5

↝ y\leq 2x-5 means that the shade/area is below the graph as shown in the first picture.

y\leq -\frac{1}{2}x-3

↝ x-intercept

-\frac{1}{2}x-3=0\\-x-6=0\\-x=6\\x=-6

↝ y-intercept

y = -3

↝ Since it's "≤" therefore. The shade/area is below the graph. For second picture.

First picture is first inequality

Second picture is second inequality.

Scarlett is throwing a end of the year party for 2013
galben [10]

Answer:

7.5 pounds.

Step-by-step explanation:

the answer is 7.5 ponds because if each slider has 2 oz. then we can find the total number of oz. needed by multiplying by 60. This gets 120 oz that Scarlett needs in total. Since there are 16oz in a pound we divide 120 by 16 to find the number of pounds needed.

How can you use formulas you already know to find the area and perimeter of a composite figure? The six lane track shown in the
evablogger [386]

The area of the composite figure = 10,874.1 sq. m.

The perimeter of the composite figure = 406.9 m

<h3>What is the Area and Perimeter of a Rectangle and Circle?</h3>

Perimeter of a rectangle = 2(length + width)

Area of a rectangle = length × width

Perimeter of a circle = 2πr

Area of a circle = πr²

<h3>What is Area of the composite figure?</h3>

The figure is made up of two semicircles (1 full circle) and a rectangle.

Area of the composite figure = area of circle + area of rectangle

= πr² + length × width

r = 36.5 + 1.2 = 37.7 m

length = 85.0 m

width = 2(36.5) + 2(1.2) = 75.4 m

Substitute

Area of the composite figure = π(37.7)² + 85.0 × 75.4 = 10,874.1 sq. m.

<h3>What is Perimeter of the Composite Figure?</h3>

Perimeter of the composite figure = perimeter of circle + 2(length of the rectangle)

= 2πr + 2(L)

Plug in the values

= 2π(37.7) + 2(85.0)

Perimeter of the composite figure = 406.9 m
