The area of a square is tripled by adding 10 cm to one dimension and 12 cm to the other. Determine the side length of the square
Rina8888 [55]
Area = length *width
A = x²
3x² = (x+10)(x+12)
3x² = x²+10x+12x+120
3x² = x²+22x+120
3x²-3x² = x²+22x+120-3x²
0 = -2x²+22x+120
Factor to solve for x: 
-2(x²-11x-60)
(x+4)(x-15)
x = -4  & x = 15 but we can't have a negative length so we eliminate 4. The length of the square is 15 cm.

Please answer ASAP<br><br> 5x−29&gt;−34 OR 2x+31&lt;29
elena-14-01-66 [18.8K]

Answer:

x > -1 or x < -1

Step-by-step explanation:

For the first equation, 5x-29 > -3

Step 1: Move the constant to the right and change its sign

5x-29 > -34

5x > -34+29

Step 2: Calculate the sum

5x > -34+29

5x > -5

Step 3: Divide both sides of the inequality by <em>5</em>

5x > -5

x > -1

<em><u>Answer</u></em><em><u>:</u></em> -1

For the second equation, 2x+31 < 29

Step 1: Move constant to the right and change its sign

2x+31 < 29

2x < 29-31

Step 2: Calculate the difference

2x < 29-31

2x < -2

Step 3: Divide both sides of the inequality by 2

2x < -2

x < -1

<em><u>Answer</u></em><em><u>:</u></em> x < -1

The mean exam score for the first group of twenty examinees applying for a security job is 35.3 with a standard deviation of 3.6
babymother [125]

The scores of two groups can be compared using coefficient of variation;

Coefficient of variation (C.V.) = (Standard Deviation/ Mean) × 100%;

For Data set 1;

Standard deviation = 3.6

Mean = 35.3

C.V. = (3.6/35.3) × 100%;

       = 10.19%

For Data set 2;

Standard deviation = 0.5

Mean = 34.1

C.V. = (0.5/34.1) × 100%;

       = 1.46%
