Answer:
A. n = 5
Step-by-step explanation:
S = n² + n
When S = 30:
n² + n = 30
Subtract 30 from both sides: n² + n - 30 = 0
Factorize: (n - 5)(n + 6) = 0
Therefore n = 5 or -6
As n > 2, then n = 5 only
Answer:
6
Step-by-step explanation:
let's say this is the wound that's 5 inches (13cm)
~~s1~~s2~~s3~~s4~~s5~~s6~
(s in here represents sutures)
Answer: A. They are both incorrect
Step-by-step explanation:
x=3√2
y=6
z=3√2
-----------------------
45-45-90=1:1:√2
------------------------
solve for x
x is the side accordingly to 90 in the smaller triangle, so it should be the [45] side times √2
3×√2=3√2
-----------------------
solve for y
y is the side accordingly to 90, so it should be the [45] side times √2
3√2×√2=6
----------------------
solve for z
z is the side accordingly to 45 in the bigger triangle, x is also accordingly to 45 in the bigger triangle
z=x
z=3√2
