Excercise 1:
No, this is not simplified fully. The full answer would be <span>−7dk+14d−21k</span>−7, not <span>14d - 9 - 21k - 7dk + 2. So, it is not equivalent.
</span><span>
Excercise 4:
</span><span>7dk (2 - 3 - 1) - 7
</span>
Just multiply 7dk into (2) (-3) and (-1)
you'd get:
<span><span>−<span>14dk</span></span>+</span>−<span>7 after simplifying it fully.

p = parameter
w = width
w+2.75
p = 2w+2(w+2.75) = <span>4w</span>+<span>5.5 = 30
Answer to the last one:
w = 6.125</span>
That's the simplest it can go.
Answer:
The area of the label is 
Step-by-step explanation:
step 1
Find the radius
we know that
The volume of the cylinder (can of tuna) is equal to
In this problem we have
substitute and solve for r
Simplify
step 2
<em>Find the lateral area of the can</em>
The lateral area of the cylinder (can of tuna) is equal to
we have
