To calculate the answer, we subtract $ 14 from the first CD to the total amount spent, which is $ 86.
So:
$ 86- $ 14 = 72
The rest of the CDs cost $ 12.
Then we divide $ 72 between $ 12
$ 72 / $ 12 = 6.
That means that 6 CDs were bought at $ 12 plus the first one bought at $ 14.
So the number of CDs that María bought was 7
Answer:
D
Step-by-step explanation:
Factor the numerators/ denominators
10 - 5 = 5(2a - 1) ← common factor of 5
4a² - 1 = (2a - 1)(2a + 1) ← difference of squares
[ Change ÷ to × and turn second fraction upside down ]
=
× 
[ cancel the factor (2a - 1) on the numerator/denominator ] leaving
=
= 
It’s b my I’m pretty sure
Answer:
and 
Step-by-step explanation:
Alright, lets get started.
The given equation is :

Adding 8 in both sides, it will become


To make it perfect square, we need to add 25 and subtract 25




Adding 17 in both sides
taking square root

So,
and
