You have to use factoring by grouping.. multiply by 8 and 15 and what factors add to -14.
The factors are 6 and -20
(2x-5)(4x+3)
The answer is b because all the points lie on the graph
Step-by-step explanation:
28+29=57
57+42=99 so 99 should be your answer
5x^2 -15x-140
5(x² -(3x) -28)
5(x² +(4x-7x)-28)
5(x(x+4) -7(x+4)
5(x-7)*(x-4)
