Hello,
Using Thalès 's theorem:
Let's h the height of the monument.
If you don't know what is the Thalès's theorem,
imagine that the similar triangles.
Find the prices per ounce by dividing the dollars by the number of ounces:-
1.79 / 15 = 0.1193 dollars per ounce
1.49 / 12 = 0.1242 dollars per ounce
So the first one is the better buy.
Answer:
( 9w - 2z)^2
Step-by-step explanation:
81w^2 - 36wz + 4z^2
Rewriting as
(9w)^2 - 2 * 9 w 2z + (2z)^2
We recognize that this is a perfect square binomial
a^2 -2ab + b^2 is a perfect square binomial because it factors to (a - b)^2
let a = 9w b = 2z
81w^2 - 36wz + 4z^2 = ( 9w - 2z)^2
Answer:
-11
Step-by-step explanation:
plug -3 in x values.
h(-3) = -3^2 -2
=-11
