Find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve
K= 16
25x^2+40x+16x comes to be (5x+4)^2.
-5(x+7)<-10
-5x-35<-10
+35. +35
-4x<25
both divided by-4
x> -6.25
i flipped the sign because I divided with a negative number. and I hope you can make -6.25 into a fraction, I can't because I don't have a calculator with me :(
Answer:
Express 15 2/3 in simplest radical form 1
Yes becaus any even numbers can be represented as 2n where n is an integer
so 2n and 2m where m and n aer both integers
they both have 2 as a factor so that will be included in finding the greatest common factor
