On a given morning the temperature was 71°f. the temperature dropped 5°f and then rose 8°f. how much does the temperature need to rise or fall to return to the initial temperature of 71°f?

  fall 3°

Step-by-step explanation:

To return to the same value, the sum of rises must be the same as the sum of falls. The temperature must fall 3 °F for the total of falls to be 8 °F, the same as the rise.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
