Answer:
A
Step-by-step explanation:
Given
- 2 + 
= 6 ( isolate the radical by adding 2 to both sides )
= 8 ( square both sides )
3x - 2 = 8² = 64 ( add 2 to both sides )
3x = 66 ( divide both sides by 3 )
x = 22 → A
<span>(5x-6)(5x+6)
= (5x)^2 - 6^2
= 25x^2 - 36</span>
Answer:
20%
Step-by-step explanation:
im not really good at percentages but from what i know you first make it a fraction by adding all the numbers together to get 55(denominator). then for the numerator you take the section that they want(11). 11/55 is equal to 20/100(divide 100 by 55 and multiply the quotient by 11 to get 20). 20/100 is 20%. hope this kinda helps.
The exponents of expression one are the same as the exponents of expression two
The answer to that is 80 percent as a fraction is 8/10
