I'm having trouble with a couple of math equations here I was given to solve.
Here is my problem Solve the quation the square root of 3x - 8 minus the square root of x-4 equals 2.
and here is an example of my problem.
the square root of 2x minus 1 minus the square root of x-5 equals 3.
Isolate one of the radicals: the square root of 2x - 1 = the square root of x - 5 + 3
Square both sides: 2x-1 = x-5+6 the square root of x-5 + 9
This is as far as I got when I was trying to apply my problem to this one. I'm confused where this six came from. I don't think this program is showing all the steps.
the sum of three consecutive positive even intergers is equal to two more than seven times half the number. What are the three even positive intergers?
To me I'm imagining it looks like this.
a + b + c = 2 + 7 x 1/2n what's a,b, and c?
It's a little more confusing to me with the even numbers portion. To me just the 2 and the seven doesn't seem like enough information to solve the problem.
All help will be greatly appreciated.
