Answer:
x = -2
Step-by-step explanation:
Add 0.75x to both sides of the equation.
-0.75x -2 = 0.25x . . . . . given
-0.75x +0.75x -2 = 0.25x +0.75x
-2 = 1.00x . . . . simplify
x = -2
25-(2+5)(2+5)
25- 4+10+10+25
=66
It is important to Remember the negative exponent law.
X^-m = 1/X^m
1/10^2 = 10^-2.
