Step-by-step explanation:
Given
Required
Select 3 equivalent expressions
Express 9 as 3^2
--- This is one equivalent expression
Take 
as difference of two squares
-- This is another equivalent expression:
Solving further:
becomes
-- This is another equivalent expression:
Hence, the equivalent expressions are:
let x be how far up the wall ladder reaches
by Pythagoras theorem
x^2+5^2=13^2
x^2 =(13^2)-(5^2)
x= square root of 144
x= 12 or x =-12(rej,x>0)
hence ladder reaches 12 foot up the wall
1. Answer: 19/30 or 0.63
2. Answer: 11/20 or 0.55
3. Answer: 7/4 or 1 3/4 or 1.75
I’ll say C because they’re the same terms as in In so
In 7 + In 5 would be In 12
You only add 7 and 5 which 12 so that’s where the 12 comes from
