Check the picture below.
so, to get the area of the triangles, we can simply run a perpendicular line from the top to the base, and end up with a right-triangle with a base of 22 and a hypotenuse of 34, let's find the altitude.
so then the surface area of the triangular prism is,

The true statement is:
"The range of the function is all real numbers less than or equal to 9."
<h3>Which statements are true?</h3>
Here we have the quadratic function:
And we want to see which of the given statements are true.
The first one is:
"The domain is al real numbers less than or equal to -2"
This is false, for all quadratic functions the domain is the set of all real numbers (unless the domain is defined).
The second statement is:
" The domain of the function is all real numbers less than or equal to 9."
Also false
Third one:
" The range of the function is all real numbers less than or equal to −2"
The range of a quadratic function with a negative leading coefficient will be the set of all the values smaller than the y-value of the vertex.
In this case, the quadratic function is:
So the vertex is at:
Then the y-value of the vertex is:
So the range is the set of all real numbers less than or equal to 9.
So the above statement is false, and the final one:
"The range of the function is all real numbers less than or equal to 9."
Is the true statement.

Answer:
Step-by-step explanation:
The area of a rectangle will always be length times width or width times length, doesn't matter which way.
In this case, the width is miles and the length is
miles. So, the area is
.
So, the area is and we're done.
