Answer:
x + 15
Step-by-step explanation:
The overall length is 2x+15, and the dotted side is shown to be x shorter than that. Its length is ...
2x+15 - x = x + 15 . . . . length of dotted side
Pi is an irrational number so you cannot find that square root<span />
Multiply x - 3y = 7 by -2.
-2x + 6y = -7
2x - 6y = 12
Add.
0 = 5
No solutions.
For number 5 - .3 ( 3.60 ÷ 12 = .3)
For number 6 - .32 ( 2.56 ÷ 8 = .32)
For number 7 - 2 ( 2.36 ÷ 2 = 1.18)
So find the factors exg
if you have √36
then you factor and grouop the 2 same factors
36=2 times 2 times 3 times 3
so the square root is 2 times 3 =6
so find the factors of 32
2 times 2 times 2 times 2 times 2
the square root is 2 times 2 times √2 or
4√2
