Answer:
Step-by-step explanation:
a=0 if both x and y are each =0
for all other real values a>0
Answer: OPTION B
Step-by-step explanation:
To solve this problem you must add the areas of each rectangle that form the prism;
The area of a rectangle can be calculated with the formula:

There are three pairs of equal rectangles, then you can find the surface area of 3 rectangles and multiply each one by 2, then you obtain that the surface area of the prism is:

K= change in y/ change in x
K= (30-18)/(5-3)
K=12/2
K=6
Answer:
(x+3)^2+(y+2)^2=80
Step-by-step explanation:
-5 is the intercept since y=mx+b, b being the intercept.
