Answer:
15b + 30
Step-by-step explanation:
By expansion (6 x 2.5b) + (6 x 5)
= 15b + 30
Factor ouf 3x
3x(12x^2-5x-2)
factor
(3x)(3x-2)(4x+1)
Add 4 to both sides
x - 4 < -3
x-4+4 < -3+4
x < 1
To graph this on a number line, plot an open circle at 1 on the number line. Do not fill in the open circle. Shade to the left of the open circle. The shaded region represents all x values smaller than 1.
The graph is shown below.
