Answer:
Option A. ( 9x³ - 2x - 3 )
Step-by-step explanation:
Given polynomials are ( 6x³ - 8x - 5 ) and ( 3x³ + 6x + 2)
We have to find the sum of these polynomials
( 6x³ - 8x - 5 ) + ( 3x³ + 6x + 2)
We will collect the similar terms first.
6x³ - 8x - 5 + 3x³ + 6x = 2
= ( 6x³ + 3x³ ) + ( 6x - 8x ) + ( 2 - 5 )
= ( 9x³ - 2x - 3 )
Option A. ( 9x³ - 2x - 3 ) is the correct option.
D
2372
You would do the equation 2332-372+412
Answer:a: y=4.5+0.75x
B: y=2.5+1.25x
C: 7.5
