Let M be any point in the interior region of rectangle ABCD. Prove that MA²+MC²=MB²+MD²

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

60
