It is not a right triangle.
Answer:
21.4 m²
Step-by-step explanation:
To find the surface area of this whole triangular prism, we have to look at the bases (the triangles), find their surface area, then look at the sides (the rectangles) and find theirs.
Let's start with the triangles. The area of any triangle is . The base of this triangle is 2m (because there are 2 one meters) and the height is 1.7m.
So the area of one of these triangles is 1.7m. Multiplying this by two, because there are two triangles in this prism:
Now let's find the area of the sides.
The side lengths are 2 and 3, so
, and there are 3 sides (including the bottom/floor) so .
Now we add.
m².
Hope this helped!
The answer is n + 3 over 5 = n - 1 over 2.
Answer:
8 pounds
Step-by-step explanation:
3 ft board = 2lb
12 ft board is 4 times more so
2x4 = 8 lb
Answer: It has two distinct real zeros.
Step-by-step explanation:
The formula that is used to calculate the discriminant of a Quadratic function is the one shown below:
In this case you have the following Quadractic function provided in the exercise:
Let's make it equal to 0:
You can identify that:
Knowing these values, you can substitute them into the formula and then evaluate:
Therefore, since:
You can determine that the it has two distinct real roots.
