67 / 25 x 100  =  268%

Since the triangle is a SAS situation, use the Law of Cosines:  b = 9   c = 7

a² = b² + c² - 2·b·c·cosA

a² = 9² + 7² - 2·9·7·cos46

a² = 42.473

a  =  6.5

A good equation to know is the  point-slope  equation, used when you know a point and a slope.

y - y1  =  m · (x - x1)           where m is the slope and (x1, y1) is the point.

For your problem,  m = 3  x1 = 5  and  y1 = 2:

y - 2  =  3(x - 5)

Now, it depends in what form you want your answer:

To get it into y-form:

y - 2  =  3x - 15

y  =  3x - 13

The prefix "milli" means "one one-thousandths", so to covert meters to millimeters multiply by 1000.

-y > 2/3

MUutiply both sides by -1:  (If you divide or multiply both sides of an inequality by a negative number, you                                                must change the direction of the inequality.)

-y · -1  <  2/3 · -1

y  <  -2/3

First, you will need to find the distance from A to C, which is side b.

Since you have a SAS triangle, use the Law of Cosines:

b² = a² + c² -2·a·c·cosB

b² = 63² + 91² -2·63·91·cos153.4

b² = 22502

b  =  150 mi

150 miles at 300 miles per hour  =  1/2 hour

2f² - 9f + 5  =  0

Quadratic formula:  x  =  ( -b ± √(b² - 4ac) ) / (2a)

In this case:  a  =  2         b  =  -9         c = 5

x =  ( --9 ± √( (-9)² - 4(2)(5) ) ) / ( 2(2) )

x =  ( 9 ± √( 81 - 40 ) ) / ( 4 )

x =  ( 9 ± √( 41 ) ) / 4 

Can you use each digit only once, or can you use some of the digits more than once?

Must you use each digit?

Can you use addition, subtraction, multiplication, division, exponentiation, finding roots, factorials, and including negative signs?

In summary, what are all the rules?

Since  12 - 6  =  6:

     6 = Cloud
