Idon't know how to solve this problem i think i can dl the firts part but the 2nd one i don't know what x means the question said" evaluate the expressions below for the given values" "-2x2+1 for x=-3" the firts part gives me 9 bit idk what to do with the "for x=-3"

In the equation -2x^2 + 1
We're supposed to substitute x by the given value which is -3 in this case.
-2x^2 + 1 = -2(-3)^2 + 1
= -2(9) + 1
= -18 + 1
= -17

neither i nor ii 56 / 4.9 = 11.91489362 and 82 / (11+5) =5.125 so i is wrong

ii. (24/8+2) times 3 = 15 and (42+9)/2 =25.5

step-by-step explanation:

56

r = 78539458390583095803458309458039485093485 or just 3
