What is the surface area of the triangular prism
SIZIF [17.4K]

Answer:

Step-by-step explanation:

First I know that both triangles have an area of 24. And judging from the rectangles the height is 10 correct? If so then it would be 24+24+60+60+36. The rectangles area is 60 and the square area is 36. You then add them all together and get 224. So the answer is A.

notka56 [123]
¹/₂x + 25 = -100
<u>       - 25     - 25</u>
   2 · ¹/₂x = -125 · 2
            x = -250
<u>
Check</u>
        ¹/₂x + 25 = -100
¹/₂(-250) + 25 = -100
     -125 + 25 = -100
             -100 = -100

Your answer is correct.

The graph of y = - 1/2x +2 is positive over the interval (-♾,4) and negative over the interval (4,♾). What happens on the graph
SCORPION-xisa [38]

Answer:

There is no solution when x=4

Step-by-step explanation:

By drawing the graph, we can see that x = 4 is a vertical asymptote. An asymptote is a line in which the graph approaches it but never meets it. As a result, the graph will never approach x=4. This means there is no solution at x = 4
