Answer: LAST OPTION
Step-by-step explanation:
To solve this problem you must:
- Calculate the surface area of one of the squares, with the formula for calculate the surface area of a square, where "s" is the lenght of any side of the square, then you obtain;
- Now, you must multiply this area by 6 (6 faces of the cube), then the results is:
Answer:
y = 3x -8
Step-by-step explanation:
I find it convenient to start with a version of the point-slope form of the equation for a line. That is, for point (h, k) and slope m, ...
y = m(x -h) +k
For your m=3 and (h, k) = (3, 1), this equation becomes ...
y = 3(x -3) +1
Eliminating parentheses puts this in the form you desire:
y = 3x -8
