Answer:

3.5

Step-by-step explanation:

This is a 30-60-90 triangle so the hypotenuse is equal to 2 times \sqrt{3}.

x = 2\sqrt{3} ≈ 3.5

Answer:  -p^2-(q+r)^2

Work Shown:

I'm assuming your teacher wants you to factor as much as possible.

-p^2-q^2-r^2-2qr\\\\-p^2-q^2-2qr-r^2\\\\-p^2-(q^2+2qr+r^2)\\\\-p^2-(q+r)^2\\\\

In the last step, I used the rule that (a+b)^2 = a^2+2ab+b^2

We cannot factor any further. If the first term was p^2 instead of -p^2, then we could use the difference of squares factoring rule.

A mathematics book has 360 pages, of which 50% are on algebra, 20% on geometry and the remainder on arithmetic how many pages ar
Arte-miy333 [17]

Answer:

30% of the pages are arithmetic, or 108 pages

Step-by-step explanation:

50% are on algebra = 180 pages

360 x .5 = 180

20% are on geometry = 72 pages

360 x .2 = 72

30% are on arithmetic = 108

180 + 72 + 108 = 360 pages

50% + 20% + 30% = 100%
