The dimensions of a triangular prism are shown in the diagram. What is the
total surface area of the triangular prism in square centimeters?"

I need helppp

Step-by-step explanation:

SA = bh + (s1 + s2 + s3)H is the formula to find out the surface area

b is base, h is height (small height), s's are the sides, H is the height (longer one)

SA = 12(9) + (10 + 10 + 12)32

SA = 108 + (32)32

SA = 108 + 1024

SA = 1132

the 3rd option is right

step-by-step explanation:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
