Answer:
A-B=x^2-x+1
Step-by-step explanation:
A-B=3x^2+5x-6+(-2x^2-6x+7)
=3x^2+5x-6-2x^2-6x+7
=x^2-x+1
Answer:
31/16
or
1 15/16
Step-by-step explanation:
1/8 = 2/16
1/4 = 4/16
1/2 = 8/16
1 = 16/16
then:
1 + 1/2 + 1/4 + 1/8 + 1/16
= 16/16 + 8/16 + 4/16 + 2/16 + 1/16
=(16+8+4+2+1)/16
= 31/16
31/16 = 16/16 + 15/16 = 1 + 15/16 = 1 15/16
