MATH PLEASE CHECK IT!!2
sqrt2/sqrt10 here is what I got: sqrt (2/10)= sqrt (1/5) sqrt 0.2 * I don't think that it is right but pleasee check it.Thanks Yes, that is one way you could do it, then simplify further by taking the square root of 0.2, but you are probably supposed to simplify like this:...

Math(I Don't Get THIS!!)
15sqrt8x^16/5sqrt2x^4 *I totally need help with this one!Please help me.! I'm going to assume your problem is this: 15√(8x^16) / 5√(2x^4) You can start by simplifying what's outside the square root sign. 15/5 reduces to 3/1. We end up with this: 3√(8x...

Math Please Check It
(2sqrtx)(5sqrtx^3) Here is what I got:10sqrtx^4 *Is this correct.? This one is close but still needs to be simplified further. 10√x^4 -->you can take the square root of x^4. Can you take it from here to finish? so it will be:10sqrtx^2 No, remember you are taking the s...

Please Check My Math Work
(3sqrt5)(2sqrt10) I got:6sqrt50 Is this correct.? You can take this one step further. 6√50 can be simplified to this: 6√(25 * 2) -->you can take the square root of 25. 6 * 5 √2 = 30√2 -->this is the simplified form. thanks can you help me with my ...

3. You are sliding a big cabinet down a truck ramp for a customer. You must maintain control of the cabinet because it is very heavy. There are 2 ramps in the building. The equation of ramp 1 is y = 2x + 7 and the equation of ramp 2 is y = 3 x + 7. Which is the safest ramp to ...

How do I do this.?(Math.)
Use the Substitution method to solve the system of equations. y - 2x = -5 3y - x = 5 Solve one of the equations for x or y. Let's solve the first one for y: y - 2x = -5 y = 2x - 5 Now let's substitute 2x - 5 for y in the second equation to solve for x: 3(2x - 5) - x = ...

Another problem to check..please check my work...
(-2x^2y)^3*(5xy^3)^2=(-2x^2y)^3 = -8 x^6 y^3 *Is this correct.? (-2x^2y)^3 * (5xy^3)^2 = (-8x^6y^3) * (25x^2y^6) = -200x^8y^9 When you have the same base, you add exponents when multiplying. For example, x^2 * x^3 = x^5. When you have the same base, you multiply exponents when...
