Hello from MrBillDoesMath!
Answer:
9, 11
Discussion:
From the attachment,
P = w + l + w + l
= 2w + 2l => as l = w + 2
= 2w + 2( w+2)
= 4w + 4
= 40 (given value)
4w + 4= 40 => subtract 4 from both sides
4w = 40 -4 = 36 => divide both sides by 4
w = 36/4 = 9
This implies that l = w+2 = 9 + 2 = 11
Thank you,
MrB
5-x=2x+8 is the equation. are you solving for x or just finding the equation
When both expressions have the same value, then they are equal to each other.
<h3>What is an equivalent expression?</h3>
The equivalent is the expressions that are in different forms but are equal to the same value.
Consider the expressions 5 + 8k and 8k + 5.
Using k = 3
5 + 8k = 8k + 5
5 + 8(3) = 8(3) + 5
5 + 24 = 24 + 5
29 = 29
Using k = 5
5 + 8k = 8k + 5
5 + 8(5)= 8(5) + 5
5 + 40 = 40 + 5
45 = 45

<u>Complete question:</u>
Consider the expressions 5 + 8k and 8k + 5. Determine why the expressions are equivalent.
Using k = 3 5 + 8k 8k + 5 5 + 8(3) 8(3) + 5 5 + 24 = 29 24 + 5 = 29
Using k = 5 5 + 8k 8k + 5 5 + 8(5) 8(5) + 5 5 + 40 = 45 40 + 5 = 45
Complete the statements.
If both expressions have the same value after substituting and simplifying two different values for the variable, then they are.
The value of both expressions when k = 3 is and when k = 5 is 45, so the expressions are.
