Step 1
a. The first 10 multiples of 8 are as follows.
\(\displaystyle{8}\times{1}={8}\)
\(\displaystyle{8}\times{2}={16}\)
\(\displaystyle{8}\times{3}={24}\)
\(\displaystyle{8}\times{4}={32}\)
\(\displaystyle{8}\times{5}={40}\)
\(\displaystyle{8}\times{6}={48}\)
\(\displaystyle{8}\times{7}={56}\)
\(\displaystyle{8}\times{8}={64}\)
\(\displaystyle{8}\times{9}={72}\)
\(\displaystyle{8}\times{10}={80}\)
The first 10 multiples of 8 are \(\displaystyle{8},{16},{24},{32},{40},{48},{56},{64},{72},{80}\).
Step 2
b. The first 10 multiples of 12 are as follows.
\(\displaystyle{12}\times{1}={12}\)
\(\displaystyle{12}\times{2}={24}\)
\(\displaystyle{12}\times{3}={36}\)
\(\displaystyle{12}\times{4}={48}\)
\(\displaystyle{12}\times{5}={60}\)
\(\displaystyle{12}{t}{i}{m}{e}{6}={72}\)
\(\displaystyle{12}\times{7}={84}\)
\(\displaystyle{12}\times{8}={96}\)
\(\displaystyle{12}\times{9}={108}\)
\(\displaystyle{12}\times{10}={120}\)
The first 10 multiples of 12 are \(\displaystyle{12},{24},{36},{48},{60},{72},{84},{96},{108},{120}.\)
c. From the lists in part a and b, the common multiples of 8 and 12 in the list are \(\displaystyle{24},{48},{72}.\)
d. From part c, the smallest multiple that 8 and 12 have in common is 24.

We will now add support for register-memory ALU operations to the classic five-stage RISC pipeline. To offset this increase in complexity, all memory addressing will be restricted to register indirect (i.e., all addresses are simply a value held in a register; no offset or displacement may be added to the register value). For example, the register-memory instruction add x4, x5, (x1) means add the contents of register x5 to the contents of the memory location with address equal to the value in register x1 and put the sum in register x4. Register-register ALU operations are unchanged. The following items apply to the integer RISC pipeline:
a. List a rearranged order of the five traditional stages of the RISC pipeline that will support register-memory operations implemented exclusively by register indirect addressing.
b. Describe what new forwarding paths are needed for the rearranged pipeline by stating the source, destination, and information transferred on each needed new path.
c. For the reordered stages of the RISC pipeline, what new data hazards are created by this addressing mode? Give an instruction sequence illustrating each new hazard.
d. List all of the ways that the RISC pipeline with register-memory ALU operations can have a different instruction count for a given program than the original RISC pipeline. Give a pair of specific instruction sequences, one for the original pipeline and one for the rearranged pipeline, to illustrate each way.
Hint for (d): Give a pair of instruction sequences where the RISC pipeline has “more” instructions than the reg-mem architecture. Also give a pair of instruction sequences where the RISC pipeline has “fewer” instructions than the reg-mem architecture.

Sheila is in Ms. Cai's class . She noticed that the graph of the perimeter for the "dented square" in problem 3-61 was a line . "I wonder what the graph of its area looks like ," she said to her teammates .
a. Write an equation for the area of the "dented square" if xx represents the length of the large square and yy represents the area of the square.
b. On graph paper , graph the rule you found for the area in part (a). Why does a 1st−quadrant graph make sense for this situation? Are there other values of xx that cannot work in this situation? Be sure to include an indication of this on your graph, as necessary.
c. Explain to Sheila what the graph of the area looks like.
d. Use the graph to approximate xx when the area of the shape is 20 square units.

When a gas is taken from a to c along the curved path in the figure (Figure 1) , the work done by the gas is W = -40 J and the heat added to the gas is Q = -140 J . Along path abc, the work done by the gas is W = -50 J . (That is, 50 J of work is done on the gas.)
I keep on missing Part D. The answer for part D is not -150,150,-155,108,105( was close but it said not quite check calculations)
