Sleep experts believe that sleep apnea is more likely to occur in men than in the general population, that is the percentage of men who suffer from sleep apnea is greater than 8%. To test this claim, one expert examined 75 men and found that 10 of these men suffer from sleep apnea. What are the Null and Alternative Hypotheses

length 15 width 9

Step-by-step explanation:

Then the length can be represented by the following expression: (x + 6)

Since area is equal to length times width, we can write the following equation for the area:

A = length * width

135 = (w + 6) * w

Now we can solve for w after using the distributive property and factoring:

135 = (w + 6) * w

135 = w^2 + 6w

0 = w^2 + 6w - 135

This factors to:

0 = (w + 15) (w -9)

w = -15 OR w = 9
