Answer:
3x+9 < 60 where x = Audrey's age
Step-by-step explanation:
Lou says "even if you tripled you age", which means that if Audrey's age is represented by the variable x, then we would multiply it by 3 to get 3x. the next part says "and add 9". We already have the 3x, so we would just tack on a +9 to get 3x + 9. The last part says "you still wouldn't be as old as me." Given that 3x+9 represents Audrey's age, this equation would have to be less than Lou's age, which in this case is 60.
The input is the y
y = x^2 - 5
plug in what we're given
-1 = x^2 -5
add 5 to both sides
4 = x^2
take the square root of both sides
2 = x

Answer:
Step-by-step explanation:
Pretty Tall.
Tan(72) = opposite / adjacent
The opposite is the height of the building
The adjacent = 100
Tan 72 = 3.077
Tan (72) = opposite / 100
3.077 = opposite / 100 Multiply by 100
3.077 * 100 = opposite
opposite = 307.7
opposite rounded = 308
