Answer:
in simplest form the radical would be, 4 3/4
( the / is supposed to be the square root sign)
hope this helped ;D
4/3 vs 6/3
4 parts out of 3 or 6 parts out of 3
they are both out of 3
4<6
4 is bigger than 6
therefor martin buys more

Answer: A. 80
Step-by-step explanation:
8 times 10 = 80
Answer:
B) (4x-5i)(4x+5i)
Step-by-step explanation:
The expression can be treated as the difference of squares, and factored accordingly. That factoring is ...
a² -b² = (a -b)(a +b)
__
Here, we have ...
a² -b² = 16x² -(-25)
a² = 16x² ⇒ a = 4x
b² = -25 ⇒ b = √-25 = 5i
Then the factoring is ...
(a -b)(a +b) = (4x -5i)(4x +5i)
