Step-by-step explanation:
hello :
(3+i)(2+i) = 6+3i+2i+i² but : i² = -1

The answer is x equals 24
you set up a proportion new over old
so for red cars 40 over 5
since we don’t know the new for blue cars we’ll use x
so x over 3
we then make them equal to each other
40 x
—- = —-
5 3
cross multiply, then we get
120=5x
isolate the x by dividing 5 from both sides to get 24
The answer is less than or equal to -4. Because -4+8=4
