GeometryCircles

AB and AC are tangents to circle O, and OC= 5X. find OC.

AB= 14+4X

AC= 19-6x

Making clear OC is just the radius its not the whole diameter.

Help me please! I don't know what to do after I make equal the two tangents (I know they are congruent) so I did 14+4x=19-6x and I got x=1/2

Marvin's Answer:

This is scientific notation:  A number multiplied by ten to a power.  Moreover, It is Standard Scientific Notation: the number in front is > or = to 1 and <10

Quadratic EquationsFactoringQuadratic Formula

How do you factor an equation like ax^2+bx+c if the a is negative and there is no c?

I know how to graph these kinds of equations with parabolas but cannot figure out how to find the factored, vertex, and standard forms of these equations.

Asked by John from Frisco, TX

Marvin's Answer:

Don't get confused by the fact that a is negative and c=0.  This is standard factoring.

ax^2+bx+c = (ax+b)(x)     Remember: c=0

Algebra

(X-2)/3+(X-2)/4=7/24

PLEASE SHOW ME THE STEPS TO SOLVE THIS EQUATION. I KNOW THE ANSWER IS X=5/2

Asked by SUSAN from Fort Lauderdale, FL

Marvin's Answer:

If someone tells you that the answer is x=5/2 then they should be able to show you how to get that answer.  My answer is different.

(x-2)/3 + (x-2)/4 = 7/24  I approach this by expressing everything as 24ths.  Thus I must multiply the first term by 8/8 and the second term by 6/6.  Note that 8/8 = 1  and 6/6 = 1

{(x-2)/3} {8/8} + {(x-2)/4} {6/6} = 7/24

{8(x-2)}/(3)(8) + {6(x-2)}/(4)(6) = 7/24

{8x-16}/24 + {6x-12}/24 = 7/24  now we are adding 24ths and the numerators must add

8x-16+6x-12 = 7

14x -28 = 7  add 28 to both sides

14x = 35  divide both sides by 14

x = 35/14  divide top and bottom by 7

x = 5/2
