[(25-11)+(15-9)] / 5

First you take care of the numbers in the brackets & then parenthesis.

25-11=14 and 15-9=6

Now you add both of those numbers together.

14+6=20

Now you divide.

20/5
=4

Do what's inside the parenthesis first then the brackets, then take that final result and divide by 25

[(25-11)+(16-9)]/25
[(14)+(7)]/25
21/25
= .84

What is the area of the figure?
Kipish [7]

Answer:

17.98 square meters

Step-by-step explanation:

find the area of rectangle

length x width

6.2x1.8= 11.16

find area of triangle

base x height x 1/2

base= 6.2

height= 4-1.8= 2.2

area=2.2 x 6.2 x 1/2 = 6.82

add both together to get area of figure

6.82 + 11.16 = 17.98

Determine the approximate value of x.
yarga [219]

Answer:

  C.  6.736

Step-by-step explanation:

The unmarked angle is 180-80-40 = 60 degrees. Given the angles of the triangle and one side length there is enough information to use the Law of Sines to solve the triangle--eliminating choice D.

The angle opposite x is larger than the angle opposite 5, so <em>x will be larger than 5</em>. That leaves only answer choice C: 6.736.

___

If you want to actually use the law of sines to determine x, you know that ...

  x / sin(60°) = 5 / sin(40°)

  x = 5·sin(60°)/sin(40°) . . . . . . multiply by sin(60°)

  x ≈ 6.736
