Example Question #11 : How To Solve For A Variable As Part Of A Fraction
Solve for x:
In order to solve for x, you must cross multiply the ratio first. They will be equal to each other.
, you then can add 3x to both sides and 402 to both sides as well. You are left with:
divide both sides by 9 to get the final answer:
Example Question #1 : How To Use Foil With Exponents
If , which of the following could be the value of ?
Take the square root of both sides.
Add 3 to both sides of each equation.
Example Question #2 : How To Use Foil With Exponents
Simplify:
= x3y3z3 + x2y + x0y0 + x2y
= x3y3z3 + x2y + 1 + x2y
= x3y3z3 + 2x2y + 1

Example Question #4 : How To Use Foil With Exponents
Which of the following is equivalent to 4c(3d)3 – 8c3d + 2(cd)4?
None of the other answers
2(54d2 – 4c2 + 2c3 * d3)
2cd(54d2 – 4c2 + c3 * d3)
cd(54c * d3 – 4c3 + c2 * d2)
2cd(54d2 – 4c2 + c3 * d3)
First calculate each section to yield 4c(27d3) – 8c3d + 2c4d4 = 108cd3 – 8c3d + 2c4d4. Now let's factor out the greatest common factor of the three terms, 2cd, in order to get: 2cd(54d2 – 4c2 + c3d3).
