▹ Answer
<em>(3x + 4) * (4x - 5)</em>
▹ Step-by-Step Explanation
12x² + x - 20
<u>Rewrite </u>
12x² + 16x - 15x - 20
<u>Factor out</u>
4x(3x + 4) - 15x - 20
4x(3x + 4) - 5(3x + 4)
<u>Factor</u>
(3x + 4) * (4x - 5)

Answer:
75.5
Step-by-step explanation:
To calculate the mean we use
mean = 
To calculate the mean for class B we require their score
Using the mean for class A
= 67.8 ( multiply both sides by 25 )
score = 67.8 × 25 = 1695
Similarly using the mean for all 55 students
= 72 ( multiply both sides by 55 )
total score = 72 × 55 = 3960
Hence score for class B = 3960 - 1695 = 2265
mean for class B = 
= 75.5
