4/7 = 8/14 = 12/21 = 16/28, etc
Answer:
26/5
Step-by-step explanation:
(2)(2)(4)/5 −8+10
(4)(4)/5−8+10
=16/5−8+10
=−24/5+10
=26/5
Alternate form
5.2
Answer: 20

Divide the number of students by the number of rows,
180/9=20
Answer:
(3x-2)(4x-1)
Step-by-step explanation:
1. take the a and the c value and multiply them together to isolate x^2. it should be x^2 -11 +24.
2. find what multiplies to 24 and adds up to -11. its -8 and -3.
3. factor like normal and get (x-8) (x-3)
4. divide the -8 and -3 in the factors by 12 (the original a value)
-8/12 = -2/3 and -3/12 = -1/4.
5. the denominator gets moved to the x value to get (3x-2)(4x-1)
