Answer:
C
Step-by-step explanation:
If we make an equation for this we get:
(36 3/4 + 36 3/8 + 37 1/2 + z) / 4 = 36 5/8
Then we multiply to only get the parentheses:
36 3/4 + 36 3/8 + 37 1/2 + z = 146.5
Then we combine like terms which makes:
110.625 + z = 146.5
Then we subtract on both sides which makes:
z = 35.875
Make it into a fraction it makes: 35 7/8
(x−1)(x+6)(2x+7); 2x+7
2x3+17x2+23x−42
=(x−1)(x+6)(2x+7)
i could just simplify the first part
329.84
(38 x 4) 2.17
answer is zero in the following
(8^6) × (8^9)=
