Answer:
Step-by-step explanation:
Lets pick to columns in the table
Lets so (6,228) and (7,266)
To find the slope you need to do y1-y2/x1-x2
7-6/266-228=1/38.
1/38 is the slope.
y=1/38x+b
to find B you have to plug any of the y with the corresponding x values back in and solve for b.
Lets choose 228.
228=1/38(6)+b
228=6/28+b
(28/6)(228)=b
b=1064
the equation will be y=1/38x+1064
5x=30
5x/5=30/5
x=6
5x=30 divide each side by 5 5x/5=x = 30/5= 6 meaning x=6
When adding these just add common numbers for instance those with the i variable and then the coefficients. We will get (-7+7i)
2(L * W) + 2(L * H) + 2(W * H) = surface area
