Answer:
x=9
Step-by-step explanation:
since the location of 4x+2 and 7x-25 is across from each other that means that they are equal to each other so you have to set them equal to each other by doing 4x+2=7x-25 then you add like terms you add 25 and 2 together which gives you 27 and the equation will look like 4x+27=7x and then you subtract 4x from 7x which gives you 3x and u get the equation 27=3x now you divide 27 by 3 and get 9 so the equation will be x=9

Answer: A^2</h3>
You subtract the exponents using the rule
(x^y)/(x^z) = x^(y-z)
This rule only applies if both bases are the same.
The commutative property, because you are simply moving the terms around without actually changing the overall value.
Use the quadratic formula for the roots:
x = [ (-5) +/- sqrt (5^2 - 4*1*-5) ] / 2
