1420 bricks
Step-by-step explanation:
10 rows x 142 bricks in each row = 1420 bricks
9514 1404 393
Answer:
Step-by-step explanation:
These "special" right triangles have side length ratios that it is useful to remember.
<u>45°-45°-90° triangle</u>
Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.
x = 18√2
<u>30°-60°-90° triangle</u>
Shortest to longest, sides have the ratios ...
1 : √3 : 2
That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.
y = 18√3
z = 2·18 = 36
Answer:
d. 
Step-by-step explanation:
<----- This is your answer
Hope this helps!
Y = 2x^2 - 4x + 2
y = 2(x^2 - 2x + 1)
2(x - 1)^2 = = 0
so the graph will just touch the x axis at x = 1
So there is one zero duplicity 2.
