Answer:

x = 7

Step-by-step explanation:

We can tell by looking at this triangle that this is a <u>45 45 90 triangle.</u>

In this situation, the hypotenuse is $x\sqrt{2}$ and the legs are both $x$ .So if we look at the hypotenuse, we can tell that x, or the leg of the triangle, is 7.

45 45 90 triangles: This is a special triangle in which the angles of the triangle are 45 45 and 90 degrees. This means that the hypotenuse will be $x\sqrt{2}$ and the legs of the triangle will be $x$ . You can usually use the Pythagorean theorem to solve the missing sides.

Answer:

$3x^{3}+15x^{2}+x+5$

Step-by-step explanation:

We are told that the area of the bag can be represented by the function $f(x)=3x^{2} +1$ and as the bag is raised up its height can be represented by the function $g(x)=x +5$ .

Since we know that we can find volume of cuboid by multiplying base area to its height. We are given area and height of bag as functions. Now we will find volume of the bag by multiplying these functions.

$\text{Volume of collapsible bag}=f(x)*g(x)$
