Answer:</h3>
c) (A, B, C) = (2, 2, -43)
<h3>
Step-by-step explanation:</h3>
Multiply the given equation by 3:
... 2(x -4)(x +5) = 3
Multiply the binomial terms:
... 2(x^2 -4x +5x -20) = 3
Collect terms and use the distributive property:
... 2x^2 +2x -40 = 3
Subtract 3 to put into general form:
... 2x^2 +2x -43 = 0
The coefficients A, B, C are the coefficients of the general form equation, left to right:
... A = 2; B = 2; C = -43 . . . . matches selection c)
Answer:
C 2b3 + b2 - 2b - 380
Step-by-step explanation:
Given:
Factory A: 2b^3 – 3b^2 + b - 120
Factory B: 4b^2 – 3b – 260
The company's total output = factory A + factory B
= (2b^3 – 3b^2 + b - 120) + (4b^2 – 3b – 260)
= 2b^3 – 3b^2 + b - 120 + 4b^2 – 3b – 260
Collect like terms
= 2b^3 – 3b^2 + 4b^2 – 3b + b - 120 - 260
= 2b^3 + b^2 - 2b - 380
C. 2b^3 + b^2 - 2b - 380
Option C is the correct answer
