Answer:
(x + n)^2
Step-by-step explanation:
Okay! Let's get this going!
(x + n ) ^2 is correct because first we get
x^2 and n^2. Yet we need to add one more part to this to make it true which is x * n. We multiply this by two since according to the formula (a + b)^2 = a^2 + 2ab + b^2

The dashed line labeled as 6 is the diameter of the circular part of the figure.
The circumference of a circle is it's perimeter, so we need to find half the circumference first.
The formula for circumference is PI x diameter, since we need half we will divide the total circumference by 2.
Circumference = 3.14 x 6 = 18.85 / 2 = 9.425
Now we add that to the other 3 dimensions for total perimeter:
9.425 + 9 + 9 +6 = 33.425
You may need to round the answer, you didn't say if it needed to be rounded a certain way.
Answer: Part A the answer is yes and Part B the answer is no.
Step-by-step explanation:
Part A when you divide 7 by 2 you get 3.5 and if you multiply that number by the rest of the numbers and you get the number beneath the other number.
Part B when you divide 8 by 5 you get 1.6 and if you multiply that number by the rest of the numbers and then you don't get the number beneath the other number.
Danche!
