Answer: $49\ ft^3$

Step-by-step explanation:

The volume of rectangular prism is given by :-

$\text{Volume}=l*w*h$ , hwre l is the length , w is width and h is height of prism.

The given dimensions of rectangular prism :

Length : 2 ft

Width : 7 ft.

Height : 3.5 ft.

Now, the volume of rectangular prism is given by :-

$\text{Volume}=7\times2\times3.5\\\\\Rightarrow\text{Volume}=49\ ft^3$

Hence, the volume of this right rectangular prism = $49\ ft^3$

For this case we must find the solution of the following quadratic equation:

$x ^ 2 + 5x + 7 = 0$

Where:

$a = 1\\b = 5\\c = 7$

Then, the solution is given by:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

Substituting the values:

$x = \frac {-5 \pm \sqrt {5 ^ 2-4 (1) (7)}} {2 (1)}\\x = \frac {-5 \pm \sqrt {25-28}} {2}\\x = \frac {-5 \pm \sqrt {-3}} {2}$

By definition we have: $i ^ 2 = -1$

$x = \frac {-5 \pm \sqrt {3i ^ 2}} {2}\\x = \frac {-5 \pm i \sqrt {3}} {2}$

Thus, we have two complex roots.

Answer:

The equation has no real roots.

Drag numbers to the table so it shows a proportional relationship between x and y.

Answer:

7.5 30

45 180

Step-by-step explanation:

The given line has x = 1.25 and y = 5.

y/x = 5/1.25 = 4

x is multiplied by 4 to get y since 1.25 * 4 = 5.

That means the equation is

y = 4x

For a proportional function, every value of x must be multiplied by 4 to get y.

x = 7.5

y = 4x = 4(7.5) = 30

7.5 30

We need to find the values for the last line.

11 * 4 = 44

There is no 44

13.75 * 4 = 55

There is no 55.

17.5 * 4 = 70

There is no 70

30 * 4 = 120

There is no 120.

45 * 4 = 180

There is a 180.
