The sum of −15x2 −5x + 11 and another polynomial expression is −9x2 + 3x −10. what is the other polynomial expression? a)24x2  + 8x − 8b)6x2  + 8x − 21c)− 24x2  + 8x + 8d)− 24x2  + 8x − 8

B

Step-by-step explanation:

To find the missing term, subtract the given term from the sum.

(−9x2 + 3x −10)−(−15x2 −5x + 11)

−9x2 + 3x −10 + 15x2 + 5x − 11

6x2 + 8x − 21

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

x/3-10=8

x/3=18

x=48
