<h3>Answer:  28</h3>

=========================================================

Explanation:

Everywhere you see an x, replace it with 6

f(x) = 5x - 2

f(6) = 5*6 - 2

f(6) = 30 - 2

f(6) = 28

Remember that 5x is the same as 5*x or "5 times x". So that's why 5x turned into 5*6 after replacing x with 6. After every x is replaced, you follow the order of operations PEMDAS to simplify.

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 5x - 2

f(6) is x = 6

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em> [Function]:                                                                                f(6) = 5(6) - 2
  2. Multiplication:                                                                                                    f(6) = 30 - 2
  3. Subtraction:                                                                                                       f(6) = 28

Determine whether each set of numbers can be the measure of the sides of a triangle. If so, classify the triangle as acute, righ
ElenaW [278]

The following set of numbers 2√3, 4√2, and 3√5, can be the measures of the sides of an obtuse triangle.

A triangle is a polygon with three sides and three vertices.

To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.

let a = 2√3, b = 4√2, and c = 3√5

a + b > c     2√3 + 4√2 > 3√5     9.12 > 6.71     True

a + c > b     2√3 + 3√5 > 4√2     10.17 > 5.66    True

b + c > a     4√2 + 3√5 > 2√3     12.37 > 3.46     True

To know what type of triangle based on the length of its side:

1. Take the sum of the squares of the two smaller sides.

(2√3)^2 + (4√2)^2 = 44

2. Compare it to the square of the largest side.

(3√5)^2 = 45

44 < 45

If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.

if they are equal, it is a right triangle

if they are smaller, then it is an obtuse triangle.

Hence, 2√3, 4√2, and 3√5 can be the measure of the sides of an obtuse triangle.

Answer:

4. 8.0

5. 27.6

6. 35.5 degrees

Step-by-step explanation:

#4- Cos 48= x/12

0.669131= x/12

x=8.0

#5

Sin 78= 27/x

0.978=27/x

0.978x=27

x=27.6

#5

Tan X= 15/21

tan x= .714

inverse tan= 35.5 degrees

A rectangular photograph is surrounded by a border that is 1 inch wide on each side. The total area of the photograph and the bo
My name is Ann [436]

if 1 inch is added, you would add 2 inches to to each side of rectangle.  

You would have: W+2, and, L+2,  

Now let W+2 = x and, L+2 = y  

Total area =  x*y=M  

If 1 inch is added again, like above you add 2 inches to both sides, you would then have:

(x+2)(y+2)=M+52;  

xy+2x+2y+4=M+52;  

xy=M

2x+2y=48  

x+y=48/2=24  

Now solve :

W+2+ L+2=24  

W+L=20  

The perimeter is 2(W+L)=20*2 = 40 inches.
