Solve -1/3x > 5 a) x < -15 b) x > -15 c) x > -5/3 d) x< -5/3

Step 1. Simplify 1/3x to x/3

-x/3 > 5

Step 2. Multiply both sides by 3

-x > 5 * 3

Step 3. Simplify 5 * 3 to 15

-x > 15

Step 4. Multiply both sides by -1

x < -15

Your answer is A.

The width is 13 and the length is 26.

Explanation:

Area of rectangle = length x width

Let x be the width of the rectangle and 2x be the length of the rectangle.

2x * x= 338

2x² = 338

x² = 338/2

x² = 169

x² - 169 = 0

(x)² - (13)² = 0

(x-13)(x+13) = 0

x - 13 = 0 or x + 13 = 0
x = 13 or -13

-13 is rejected, as length or width cannot be negative.

Ans:The width is 13 and the length is 2 x 13 = 26.
