We just count squares. Those two half-squares will add to one whole square. So this is a 3x4 rectangle plus a triangle of area 2.

Answer: Choice A

$\frac{\sqrt{6}+\sqrt{2}}{4}$

========================================================

Work Shown:

$\cos(30) = \frac{\sqrt{3}}{2}$

$\cos(\frac{x}{2}) = \sqrt{\frac{1+\cos(x)}{2}$

$\cos(\frac{30}{2}) = \sqrt{\frac{1+\cos(30)}{2}$

$\cos(15) = \sqrt{\frac{1+\frac{\sqrt{3}}{2}}{2}$

$\cos(15) = \sqrt{\frac{\frac{2}{2}+\frac{\sqrt{3}}{2}}{2}$

$\cos(15) = \sqrt{\frac{\frac{2+\sqrt{3}}{2}}{2}$

$\cos(15) = \sqrt{\frac{2+\sqrt{3}}{4}}$

$\cos(15) = \frac{\sqrt{2+\sqrt{3}}}{\sqrt{4}}$

$\cos(15) = \frac{\sqrt{2+\sqrt{3}}}{2}$

$\cos(15) = \frac{0.5\sqrt{6}+0.5\sqrt{2}}{2}$

$\cos(15) = \frac{\sqrt{6}+\sqrt{2}}{4}$

I dont understand please help

$2 \frac{1}{2}+(-2\frac{1}{4})$

This is equal to:

$2\frac{1}{2}-2\frac{1}{4}$

When you add a negative number, it turns into subtraction.

First, I would change it to mixed numbers:

$\frac{5}{2}-\frac{9}{4}$

Now, you need to change the denominators to make sure they are the same on both fractions. I changed the first fraction's denominator to 4 so they match. You can do this by multiplying the numerator by 2:

$\frac{10}{4}-\frac{9}{4}$

Now, you simply subtract:

10-9=1

1/4 is your answer.

I hope this helps :)

Janine has job offer sat two companies. One company offers a starting salary of 28,000 with a raise of 3,000 each year. The othe

DochEvi [55]

28,000 +3,000= 31,000 +3,000 = 34,000 +3,000 = 37,000 +3,000 = 40,000 +3,000 = 43,000 + 3,000 = 46,000

36,000 +2,000= 38,000 +2,000 = 40,000 +2,000 = 42,000 +2,000 = 44,000 +2,000 = 46,000

THE SALARY WOULD BE 46,000
IT WOULD TAKE 6 YEARS

I hope i did that right
