Answer:
is this all what u where given
Okay so first of all you are going to cross multiply, which is simply multiplying diagonally across so (6x×5 and 25×3) then you just answer each part and set them equal to each other so (30x=75). Then you just divide 30 on each side which ends up being (x=2.5)
When you have an absolute value equation like this, you drop the absolute value signs and change the sign of the value opposite of x.
For instance,
|x| = 3
Let's drop the || signs.
x = 3
This is one solution. Let's change the sign of 3 now.
x = -3
In conclusion,
x = 3, -3
Answer:
x² +18x +81
Step-by-step explanation:
(a+b)²=a²+b²+2ab
(x+9)² = x²+9²+2*x*9= x² +18x +81
Is the answer a, b, c, or d? I think it is a.
