Answer: 13

Step-by-step explanation:

Area = 165

Area of square is :

Area = length × length

Let length be l

165 = l ^ 2

Square both side

l = sqrt(165)

l = 12.85

l = 13 to the nearest whole number

Solve for x<br><br> -0.3(0.7x - 0.9) = -1.83<br><br> A.) -10<br> B.) -1<br> C.) 1<br> D.) 10
Licemer1 [7]
Hello!

That problem looks pretty messy... let's clean it up! :D

so we have this   ----->  -0.3(0.7x - 0.9) = -1.83        let's get simplifying
 
-0.21x + 0.27 = -1.83    ----->    I distributed the -0.3 among 0.7x and -0.9
-0.21x = -2.1                  ----->    I subtracted 0.27 on both sides of the equation
<u>x = 10</u><u />                             ----->    I divided -0.21 on both sides of the equation

The answer you're looking for is D!

I hope this helps! :D
