<h3>
Answer: 208</h3>
Work Shown:
S = sum of the first n terms of an arithmetic sequence
S = (n/2)*(firstTerm + nthTerm)
S = (8/2)*(firstTerm + 8thTerm)
S = 4*(6 + 46)
S = 4*52
S = 208
There are so solutions because they don’t intersect

11. 28*21 = 588 cubic feet
12. 16*9/3 = 48 pi ~150.72 ~ 151 cubic inches
13. 9*9*14/3 = 378 cubic yards
Answer:
see below
Step-by-step explanation:
There are no variables x or y or z in the given expression, so all but the answer shown below are irrelevant.
The denominator factors as ...
ab³(a² +ab +b²)
so the restrictions are that these factors cannot be zero. The cases listed in the answer choice shown are the cases that are <em>not allowed</em>.
