Answer:
31.1
Step-by-step explanation:
This is an isosceles triangle. Let us name the unnamed side y. y will also equal 22. We also know that this is a right triangle so using the pythagorean theorem we can calculate x. x = √(22^2+22^2) so x = 31.1.
Answer:
45
Step-by-step explanation:
n/15=30
therefore n=450
hence n/10 = 45
Answer:
B.) 166
Step-by-step explanation:
10 x 2 = 20
12 x 10 = 120
13 x 2 = 26
20 + 120 + 26 = 166
Answer:
1+pi/2, 5/2, square root of 12-1, 2.25. Let me know if this is correct!
Step-by-step explanation:
<h2>8 unit tiles should be added</h2>
Step-by-step explanation:
Function given is
. We wish to add more unit tiles to the function so that it becomes a complete square.
Since the given function is of order 2, the side of the square will be order 1. Let us assume a general order 1 expression
to be the side of the square.
As the function forms the square after adding some
unit tiles, 

From comparision, 
∴ 8 more unit tiles are required to complete the square.
