Step-by-step explanation:
2x+19=x+23
We simplify the equation to the form, which is simple to understand
2x+19=x+23
We move all terms containing x to the left and all other terms to the right.
+2x-1x=+23-19
We simplify the left and right sides of the equation.
+1x=+4
We divide both sides of the equation by 1 to get x.
x=4
Answer:
<h2>|-4.5| = 4.5</h2>

|a| = a for a ≥ 0
|a| = -a for a < 0
therefore
|-4.5| = -(-4.5) = 4.5
Answer:
-4 < x ≤ 9
Step-by-step explanation:
It would be 90(4 sides)= 360 ft
or 90ft+90ft+90ft+90ft=360ft
Use the formula a = a+b/2h
