An example of a unit rate would be driving a car at 50 miles per hour. 50 miles per every 1 hour is a unit rate.
Again here we're using like terms
a) -2x² + 12x² = 10x² (they have the same term that's why I grouped them together)
-4x + 2x = -2x
13 - 25 = -12
So the final answer is 10x² - 2x -12
b) 7x² - (-7x²) = 7x² + 7x² or 14x²
4x - (-3x) = 4x + 3x or 7x
-26 - 15 = -41
The final answer to this one is 14x² + 7x - 41
Answer:27x^6 /16
Step-by-step explanation:27x^3 x x^7 divided by 16x^4
then simplify the expression which will be 27x^3 x x^3 divided by 16
then calculate the product which is x^3 x x^3 which is x^6 so your answer is 27x^6/16.
