Answer:
40 feet
Step-by-step explanation:
40 feet tall
6/2 =3
?/2 =20
*2 *2
? = 40
you do inverse operations because 6 divided by 2 is 3... the ? is the variable for how tall the building is... ? divided by 2 = 20 so you multiply 2 and 20 to get the total height
The variable in that expression is x
68
The lines on both sides of the number represent absolute value. Absolute value takes any number and turns it positive no matter what.
|-68| → 68
Best of Luck!
