D is the answer
(4+8)+1 = 13
4+(8+1) = 13
Therefore equation D is true
The correct answer is C.
Because: 2.9 multiplied by 10 bags equals 29cubic ft and she needs 30 cubic ft. So she would need to buy 11 bags to make sure she has enough sand for the whole thing. 11 x 2.9 = 31.9 which ensures she has enough for the whole thing including extra in case. So you answer would be Answer C.
So, when x = -10.
If you notice, -10 is NOT in the domain (the domain is (-3,13))
so, there is no solution.
Answer:
good
Step-by-step explanation:
Answer:
0.125 or 1/8
Step-by-step explanation:
2^3 +2^-3= (2*2*2) + (1/(2*2*2))= 8 + 1/8= 8 + 0.125= 8.125
4^3 +1= (4*4*4) + 1= 64 + 1= 65
8.125/65= 0.125 or 1/8
