Describe how to use the formula to find the temperature in degrees celsius if the temperature is 86°f. what is the temperature in degrees celsius?

(86°F − 32) × 5/9 = 30°C

Substitute 86 degrees Fahrenheit into f of the formula  (F-32) x 5/9 = C.

You will get,

(86-32) x 5/9

86-32= 54 x 5/9

54 x 5/9 = 30°C

Hope this helps.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
