The surface are of a rectangular prism is:
A=2(xy+xz+yz), where x,y, and z are the dimensions of the prism, in this case:
A=2(4*6+4*8+6*8)
A=2(24+32+48)
A=2(104)
A=208 cm^2
Answer: 
Multiply both sides by -6 to undo the operation of "division of -6" that is happening to x. This will isolate x and lead to the answer. Keep in mind that multiplying both sides by a negative number will flip the inequality sign.

Step-by-step explanation:
Answer:
D. 11655
Step-by-step explanation:
First find the 90th term:
a90=a1+(n−1)d
= -4+89(3)=263
Then find the sum:
Sn = n(a1 + an) / 2
S90 = 90 (-4 + 263) /2
S90 = 23,310/2
<u>S90 = 11,655</u>
its 0.581 its pretty self explanatory so im not gonna explain
