Marcia began finding the volume of the box. Her work is shown below.

B = 5 (4) = 20 inches squared

A prism has length of 5 inches, height of 7 inches, and width of 4 inches.

Using Marcia’s work as a starting point, what is the volume of the box?

A.20 Inches cubed
B.27 Inches cubed
C.140 Inches cubed
D.280 Inches cubed

C.140 Inches cubed

Step-by-step explanation:

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
