Answer:
x^2 + 6x + 9 = 16
(x + 3)^2 = 16
x + 3 = +-4 ---> x = -7 or x = 1
9,031 ÷ 71 = 127.197183099

Since we have a rectangle triangle, then we can find the other side of the triangle using the Pythagorean theorem.
We have then:

Then the surface area is given by the sum of the areas.
Triangle of the base and the top:

Rectangle 1:

Rectangle 2:

Rectangle 3:

Finally, the surface area is:

Substituting values:
Answer:
The surface area of a right triangle prism is:
B. 132
Answer:
B
Step-by-step explanation:
2.5 + (-1.5) = 1.0
2.5 - 1.5 = 1.0
4/3x - 1/2 = 0 Given
4/3x = 1/2 Add 1/2 to both sides
x = 3/8 Multiply each side by 3/4
It is important when doing equations like these to remember that you need to multiply by the reciprocal of the fraction, not divide by it. For example, if another you have 1/2x = 1, you need to multiply by 2/1 or 2, not divide by 1/2.
