So with this, you'll be using a proportion to solve it. And here's what your equation will look like:
Firstly, you'll need to cross-multiply. Your equation will look like this:
For this, all you need to do is square root, and your answer is , however this answer can be simplified further.
In short, your answer is
x + 5 and 4x^2
Multiply the exponent of x by 2giving
The answer is
x^2 evaluates to
Multiply a and 5
Multiply a and 1
The a just gets copied along.
The answer is a
a
5*a evaluates to 5a
Boys:girls
3+1=4
1\4 x 100=25
answer=25%
Answer:
The mistake is he said"The equation has infinitely many solutions."
But based on what he was solving for, this equation does not have any solutions, so that's his mistake.
