Without solving the equation 5x^2+13x−6=0 find the sum of the squares of its roots. Could someone please explain how they got it? I know that you have to use Vieta's theorem, but I don't know what to do with that.

so, converting firstly the mixed fractions to improper fractions and then "adding".

answer: i literally just answered this question but they want me to do it again

step-by-step explanation:

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun

60: 45 =12: 9 =4: 3 so the answer is 4: 3
