Answer:
The answer is 48.9 cm^2.
Step-by-step explanation:
Let's find the surface areas of the faces other than the base;
triangle area: b x h / 2
4 x 7 = 28, 28/2 = 14
in this case, there are three faces, so 14 x 3 = 42, and we add that with the base to get 48.9
:) hope this helps!
a=c because the transitive property states so.
Answer:
The y-intercept is 3 aka. (0,3)
Step-by-step explanation:
The slope is 1 (since (6-4)/(3-1)=2/2=1)
y=1x+b
4=1+b
3=b
I'm assuming there is probably a graph that goes with this problem so here is all the info I can give you with the four choices:
If it is -1/3, the line will go DOWN 1, over 3 (just count on the graph)
If it is 3, the line will go UP 3, over 1
If it is 1/3, the line will go UP 1, over 3
And if it it -3, it will go DOWN 3, over 1
(If the slope is 3 or -3, it would be quite steep compared to a slope of 1/3 or -1/3)
Hope that helps!
