Answer:
Factoring

Completing the square

For this case seems more complicated the option completing the square because we need to do more operations and we need to know algebra. By the other hand for the Factoring case we just need to find two numbers that satisfy the conditions required.
Step-by-step explanation:
Assuming the following expression:

Factoring
For this case we want to find two values that added would be 4 and multiplied would be 3. On this case these two values are 3 and 1 because 3+1=4 and 3*1 =3. So then we can factor the expression like this:

Completing the square
For this case if we want to complete the square we need to do this:

And if we simplify this we got:

You can't solve for x based on this, but if you are talking about simplify it.
You should get 7(x+2)
Answer:
S=a^2
Step-by-step explanation:
Note all sides of a square are equal, and the formula for finding the area is length x width of which the length=a and the with =a. So S=a^2.
Answer:Look in the comments for first question a-d
1.shade 2 whole circles and 2 parts of the 3rd
2. Shade 1 whole square and 3 parts of the 2nd one got it now
Step-by-step explanation:
Volume of cone is 10
if the radius is r and height is h
while volume of cylinder is pi r 2nd power h,
volume of cone is 1/3 pi r 2nd power h.
hence with same r and h the volume of cone is one-third of that of cylinder and hence
volume of cone is 10.
