L=3w
So, the perimeter will be,
P= 2L + 2w
P= 2(3w) + 2w
P= 6w + 2w
P= 8w units
Answer:
3x+8
Step-by-step explanation:
First, we can write the sum into a <em>mathematical expression</em>:
<em>The sum of (x+5) and (2x+3)</em>
<em />
<u>(x+5)+(2x+3)</u>
<u />
<em>However, we do not need the parenthesis. It is unnecesarry here as we are just adding the two parts:</em>
<em />
<u>x+5+2x+3</u>
<u />
Using <em>commutative property</em>, we can rearrange the symbols so that the x's are with each other and the numbers are with each other:
<u>x+2x+5+3</u>
<u />
Now we can <em>simplify</em> the expression:
<u>3x+8</u>
<u />

Answer: j = -0.45
Step-by-step explanation:
2.25 – 11j – 7.75 +1.5j = 0.5j – 1
We can group similar terms:
-11j +1.5j -0.5j = -1 - 2.25 + 7.75
-10j = 4.5
j = 4.5/-10
j = -0.45
Answer: j = -0.45
