Answer:
sqrt(-8x+5)
Step-by-step explanation:
(5-8x)
-----------------
We need to rationalize the denominator
(5-8x) sqrt(-8x+5)
----------------- * ---------------
sqrt(-8x-5) sqrt(-8x+5)
(-8x+5)
The first term cancels
Second option
The radical represents the square root, i.e power ½
(5 - 8x) ÷ (5 - 8x)^½
(5 - 8x)^(1-½)
(5 - 8x)^½
(-8x + 5)^½ (just a rearrangement)
73*-2 =-146 you have to multiply the 73 to the -2
Answer: 4
Using pythagoras theorem =>
b=
b=4
