Answer is -2x^3 +25x-13

(2x² - 5x² - 6x + 7) + (5x³ + x² + 4x - 13)

= -3x² - 6x + 7 + 5x³ + x² + 4x - 13

= 5x³ - 2x² - 2x - 6

Step-by-step explanation:

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
