Answer:
B. 264
Step-by-step explanation:
Although the figure may look odd, This is just a square pyramid on it's side.
So, to find the surface area, we need to find the area of the base and the area of the faces and add them together.
To find the area of the base:
Since the base is a square, all we have to do is multiply 8 by itself.
8 * 8 = 64
The area of the base is 12.5 in^2
To find the area of the faces:
Since the faces are triangles, we have to multiply the length by the height and divide by 2.
8 * 12.5 = 100
100/2 = 50
The area of one face is 50 in^2
To find the surface area:
Add the area of the base to the area of all 4 sides.
64 + 4(50)
64 + 200 = 264
The surface area of the pyramid is B. 264 in.^2
Well two pints equal one quart
If Damian needed 3 pints
but buys in 3 quarts
then he would have to buy 3 quarts
Which 3 quarts is equivalent to 6 pints.

Step-by-step explanation:
Answer:
3ax-by+c
Step-by-step explanation:
Step1: Collect all the like terms
Like terms are similar variables, for example;
- (ax, 2ax) are all like terms since they have a common variable (ax)
- (by, -3by,by) are also like terms since they have a common variable (by)
- (c, c, -c) are also like terms since they have a common variable (c)
Step 2: Sum of all the groups of like terms
(ax+2ax)+(by-3by+by)+(c+c-c)=3ax-by+c
The answer is 3ax-by+c
