An iceberg extends 75 feet above the sea. The bottom of the iceberg is at an elevation of -247 feet. What is the height of the iceberg?
75 + 247 = 322 feet
Square root of 900
30
Is this rational or irrational?
7/8
Rational - fractions are always rational
Name the Variables then the Constants.
3b + 7w - t - 8 + 15 - 6
Variables : b,w,t
Constants : -8, 15, -6
Simplify
-6(-8n + 4) - 3( 7n - 3)
48n - 24 - 21n + 9 = 27n - 15
