Answer:
Option C is correct, i.e. 2x² +7x -4.
Step-by-step explanation:
Given is (2x-1)(x+4)
Applying FOIL method:-
F- multiply First two, O- multiply Outer two, I- multiply Inner two, L- multiply Last two.
So, (2x-1)(x+4) = 2x*x +2x*4 -1*x -1*4
(2x-1)(x+4) = 2x² +8x -1x -4
(2x-1)(x+4) = 2x² +7x -4
Hence, option C is correct, i.e. (2x-1)(x+4) = 2x² +7x -4.

Answer:
Step-by-step explanation:
1.5 + 1 13/16
O.5 = 1/2
(1+1)+(1/2 + 13/16)
2 + (8/16 + 13/16) = 2 21/16
Would it be 9 because 8 times 3 equals 24 and 3 times 3 equals 9
