Step-by-step explanation:
Given the question:
Find the error in the student's calculation. 2 cubed (2 minus 4) + 5 (3 minus 8). 2 cubed (negative 2) + 5 (5). 8 (negative 2) + 25. Negative 16 + 25. 9.
The student's error occurred here :
2 cubed (negative 2) + 5 (5)
(3 - 8) will give - 5 and not 5 as Witten by the student. The correct working is stated below :
2³(2 - 4) + 5(3 - 8)
Step 1:
8(-2) + 5(-5)
Step 2:
-16 + - 25
Step 3:
-41
Answer:
B
Step-by-step explanation:
ok so since the two pieces added together just be 96 inches, we know that
x+y=96
that already eliminates everything but B.
let's keep going though.
let's have y be the piece that is 6 inches longer than double the length of the other piece.
y=2x+6
