Answer:
d
Step-by-step explanation:
cannot be a or c cause it has a negative sign in front of it causing it to reflect over y axis. Cannot be B cause it doesn't have two coefficients with X. I also graphed it.
20? I’m not for sure maybe look in the book? That’s the answer I got and it was right
Well there are 2 pecks in 1 kenning
So that's 2 × 1 peck = 1 kenning
2 kennings in 1 bushel
That's 2 × 1 kenning = 1 bushel
2 bushels in 1 strike
That's 2 × 1 bushel = 1 strike
4 strikes in 1 quarter
That's 4 × 1 strike = 1 quarter
4 quarters in 1 chaldron
That's 4 × 1 quarter = 1 chaldron
So now substitute again and again:
4 × 1 quarter = 1 chaldron
4 × ( 4 × 1 strikers ) = 1 chaldron
4 × ( 4 × ( 2 × 1 bushel ) ) = 1 chaldron
4 × ( 4 × ( 2 × ( 2 × 1 kenning ) ) ) = 1 chaldron
4 × ( 4 × ( 2 × ( 2 × ( 2 × 1 peck ) ) ) ) = 1 chaldron
4×4×2×2×2 peck = 1 chaldron
128 peck = 1 chaldron
So that's 128 × 1 peck = 1 chaldron.
Hope this helps.

6 ÷ 2 = 3
42 + 3 = 45
It's not 7, 11, or 19. and I'm 100 % positive the answer is 45
