Answer:

x LE 6.3.

Step-by-step explanation:

For an obtuse triangle

c^2 > a^2 + b^2  where c is the longest side. So:

20^2 > x^2 + (3x)^2

400 > 10x^2

x^2 < 40

x < 6.324

x < 6.3.

You discovered you can deduct medical expenses over 6% of your income. Your income is $42,000 and you had medical expenses of $5
iren2701 [21]

No portion of your medical expenses you can deduct

Step-by-step explanation:

You discovered you can deduct medical expenses over 6% of

your income

Your income is $42,000

You had medical expenses of $567

We need to find the portion of your medical expenses you can deduct

∵ Your income = $42,000

∵ You can deduct medical expenses over 6% of your income

- Find the 6% for your income

∵ 6% of the income = \frac{6}{100} × 42,000 = $2520

∴ 6% of your income is $2520

∵ You can deduct medical expenses over 6% of your income

∴ If your medical expenses greater than $2520, then you can

   deduct the value greater than it, but if your medical expenses

   smaller than $2520, then you can not deduct any value

∵ You had medical expenses of $567

∵ $567 < $2520

∴ There is no value you can deduct from your medical expenses

No portion of your medical expenses you can deduct
