Let

x = 2.131313... Equation 1

Multiply both sides by 100 to get:

100x = 213.131313... Equation 2

Subtract equation 1 from equation 2.

99x = 211

x = 211/99

Answer: 211/99

What is the area of the hexagon?

Dominik [7]

Answer:

68 square meters

Step-by-step explanation:

The hexagon is made up of two trapezoids. Use the formula to find the area of each trapezoid then add those two areas together.

Area of a trapezoid (add the two bases together, multiply by the height then divide by 2):

$A = \frac{1}{2} (b_{1}+b_{2})h$

Top trapezoid:

$A = \frac{1}{2} (5 + 12)4\\A = \frac{1}{2} (17)4\\A= \frac{1}{2} (68)\\A = 34$

Bottom trapezoid (identical to the top trapezoid):

$A = \frac{1}{2} (5 + 12)4\\A = \frac{1}{2} (17)4\\A= \frac{1}{2} (68)\\A = 34$

Add the areas together:

34 + 34 = 68

Three consecutive integers are n, n, +1 and n+2. 4 times the sum of the least and greatest integers is 12 less than three times

raketka [301]

Answer:

The smallest integer is -4.

Step-by-step explanation:

4(n + n+2) = 3*n - 12 Combine the left

4(2n + 2) = 3n- 12 Remove the brackets

8n + 8 = 3n - 12 Subtract 3n from both sides

8n-3n + 8 = 3n-3n - 12 Combine

5n + 8 = - 12 Subtract 8 from both sides

5n = - 12 - 8

5n = - 20 Divide by 5

5n/5 = -20/5

n = - 4

n + 1 = -3

n + 2 = - 2
