Suppose you are making a model where one block represents 5 feet. About how many blocks tall is your model of the Empire State Building? What is the scale factor? The Empire State Building is just over 1,450 feet tall

Step-by-step explanation:

Scale factor is 1:5

create a proportion: 1/5 = x/1450

cross multiply: 5x = 1450

divide both sides by 5

x = 280 blocks

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
