R\Xb2-10r=-7 In Quadratic Equations

R²-10r=-7 in quadratic equations

 

Answer:

x= 10±√100-28 all over 2

Step-by-step explanation:

r²-10r=-7 transpose 7

r²-10r+7=0 then use the quadratic equation

x= -(-10)± √(-10)^2 -4(1)(7) all over 2(1)

simplified we have, x= 10±√100-28 all over 2

Compare The Two Lithospheric Crust.

Compare the two lithospheric crust.   Answer: Oceanic Lithospheric crust is more thinner and more denser while the continental Lithospheric crust is thick and less dense. Explanation: Lithosphere is composed of the crust and the upper mantle. There are two types of Lithospheric crust namely, continental crust and the other one is oceanic crust. Oceanic crust are found in the bottom of the ocean in which its particle are compressed due to increased in pressure causes its density to be more dense compared with continental crust. Continents usually located in the continental lithospheric crust, they are less dense and the particle are not that compressed compared with oceanic lithospheric crust. kindly visit the link provided below for more information: brainly.ph/question/565633 brainly.ph/question/347291 brainly.ph/question/1509352 Hope it helps....=)
