-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 :(
(2 - 5i) ( 2 + 5i) (i)
(4 + 10i -10i -25) (i)
(4 - 25) (i)
-21i
The product of 4 and -7 implies we multiply these two numbers together. Added to -12 implies we add this product to -12.
Let's do the math...
(4 x -7) + (-12)
-28 + (-12) = -40
2s+s=18, i would say d but there are no letter options
