What is the surface area of the right triangular prism shown below. for grading purposes your answer should include only numbers.

Step-by-step explanation:

You need to use the following formula for calculate the Surface area of a Right triangular prism:

Where "p" is the perimeter of the base, "h" is the height of the prism and "B" is the area of the base.

You can identify that the height is:

The area of a triangle can be found with this formula:

Where "b" is the height of the triangle and "H" is its height.

Knowing this formula, you can find the area of the base of the prism. This is:

Since the perimeter of a figure is the sum of the lenghts of its sides, "p" is:

Therefore, substituting values into the formula, you get:

a

i need the pts ignore this answer

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
