Answer:
X=3/2 or 1.732
Step-by-step explanation:
X^2-4+1=0
Combine like terms
-4 + 1 = -3
X^2-3=0
add 3 to both sides
X^2= 3
X= 3/2
What do you mean by that?
Although A is correct, C is the correct answer. If you don't get a problem like this, try to draw some of the shapes out and then draw a symmetrical line down the middle to find out if it is symmetrical.
Answer:
48
Step-by-step explanation:
Create an equation to represent this, where x is the unknown number.
+ 6 = 18
Solve for x, by first subtracting 6 from both sides:
= 12
Multiply each side by 4:
x = 48
So, the number is 48
