Answer:
length=79
width=37
Step-by-step explanation:
P=2(L+W)
2(42+x)+2(x)
84+4x=232
232-84=4x
148=4x
divide both sides by 4 to get x
x=37
length=42+37=79
width=37
Answer: $15927.183
Step-by-step explanation:
Price of good= $29,000
Trade discount = 40½ 20¼/5
The first discount will be:
= 40½ × $29000
= $11745
Then, the price after the first discount will be:
= $29000 - $11475
= $17255
Then, the second discount will be:
= $17255 × 20¼%
= $3494.14
Then, the price after the second discount will be:
= $17255 - $3494.14
= $13760.86
The third discount will be:
= $13760.86 × 5%
= $688.043
Then, the total discount will be:
= $11745 + $3494.14 + $688.043
= $15927.183
Therefore, the trade discount is $15927.183.
Answer: 
Work Shown:
I'm assuming your teacher wants you to factor as much as possible.

In the last step, I used the rule that 
We cannot factor any further. If the first term was
instead of
, then we could use the difference of squares factoring rule.
