Step-by-step explanation:
Given:
The difference between a number and 8 is 11
Find the number.
Solution:
Let the unknown number be 
The difference between the unknown number can be written as:

We are given that the difference =11
So we can write the equation to find
as :

Using additive property to solve for 
Adding 8 to both sides to isolate

Pretty easy little one hehe, hoped this helped 1m=1000mm
Answer:
D
Step-by-step explanation:
8^2 +12^2 = hyp ^2
64 +144 = hyp^2
208 =hyp ^2
Hyp = 4 root 13
x = sqaureroot of ( 18^2 + (4 root 13)^3)
x = sqaureroot of (324 +208)
x = sqaureroot of 532
x = 2 root 133
x = 23.065
x = 23
