Answer:
C and D
Step-by-step explanation:
Given
(3x - 5)² = 19 ( take the square root of both sides )
3x - 5 = ± 
( add 5 to both sides )
3x = ± + 5 ( divide both sides by 3 )
x = 
x = 
→ C
x = 
→ D
One way to I solve this is by listing all the ways it can be multiplied by:
72: 1*72, 2*36, 3*24, 4*18, 6*12, 8*9.
80: 1*80, 2*40, 4*20, 5*16, 8*10.
Group the factors that they have in common.
Which are 1, 2, 4, and 8.
After that, find the greatest common factor that they both share.
Answer: 8
Hello there!
The correct answer is option C
3x + 20x - 55 = -9
I am not sure if you wanted some more details but I hope this helps and if you do, just let me and I will edit it.
Good luck with your studies!
Happy New Year!~
Answer:
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 3 and 9 is 9
For the 1st fraction, since 3 × 3 = 9,
2
3
=
2 × 3
3 × 3
=
6
9
Likewise, for the 2nd fraction, since 9 × 1 = 9,
4
9
=
4 × 1
9 × 1
=
4
9
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
6
9
>
4
9
or
2
3
>
4
9
