4x + 2 - 3x + 5 - 2(x + 5) = (2x - 5) + (3x + 4)
4x + 2 - 3x + 5 - 2x - 10 = 2x - 5 + 3x + 4
4x - 3x - 2x + 5 + 2 - 10 = 2x + 3x - 5 + 4
- x - 3 = 5x - 1
-x - 3 = 5x - 1 is the line above recopied
+x = +x
   -3 = 6x - 1
<span>   +1 =    + 1 </span>
   - 2 = 6x
   - 2/6 = 6x/6
   - 1/3 = x, the answer

Is 0.6 repeating a rational number

julsineya [31]

Any decimal number that is repeating can be written in the form <span> $\frac{a}{b}$ </span> with b not equal to zero, so they are rational numbers.

The short answer is yes, 0.6 repeating is a rational number.

Hope this helped :)

Find the area of this triangle, round to the nearest tenth, I will give brainliest

Setler79 [48]

Answer:

59.15 in^2

Step-by-step explanation:

Using Heron's formula

semiperimeter , s = 1/2 ( 28.8+18+12) = 29.4

Area = sqrt ( 29.4(29.4-28.8)(29.4-18)(29.4-12) ) = 59.15 in^2
