-64/-8 * -3 * 25 -64/24*25 -64/600 Simplify that fraction down to lowest terms and that reduced is . . . ?

**Math 98 pre algebra**

The final answer should be 9 and 13/27.

**Algebra**

It is the same as saying -15 q to the 2nd power.

**Geometry**

Parallel lines have the same slope. 9-6/k-3 3/k-3 The slope from the other must be 5y=7-2x y= 7/5-2/5x slope = -2/5 3/k-3=-2/5 15= -2 (k-3) 15= -2k+6 9= -2k 9/-2=k

**algebra**

Don't these have to be set equal to zero somehow?!

**ALGEBRA**

-6x-18=-6x+5 0x=23 and can not have zero in the denominator. Division by zero is undefined. 15x+18=15x+18 0x=0 Well, if you take anything times zero the resulting product is zero.

**math**

You had better calculator up this one. Find out where the factorial key is on your calculator. 2010! is going to be a BIG number.

**math**

n-2 works for triangles inside of a polygon.

**algebra**

Negative exponents are better thought of as fractions. So, Cr^-2= 1/Cr^2 w/1=1/Cr^2 w times Cr^2=1 r= sqrt 1/cw
