What is 9x^2-7x subtracted from -4x^2+6

 5x^2-7x+6

Step-by-step explanation:

(−4x^2 +6)−(9x ^2 −7x)

−4x^2 +6−9x^2 +7x        Distribute the negative.

−4x^2 +6−9x^2 +7x

Combine like terms:

−13x2 +7x+6

The answer is −13x2+7x+6

where are the options?

step-by-step explanation:

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
