The inequality which makes the function have two real roots is; m > -1/5.
<h3>What is the inequality which makes the function have two real roots?</h3>
It follows from the task content that the required inequality may be determined by subjecting the determinant to greater than 0 as follows;
D > 0
b² - 4ac > 0
(2)² - 4(m)(-5) > 0
4 +20m > 0
20m > -4
m > -4/20
m > -1/5

A cube and a rectangle prism both have 8 vertices
An equation that can be used to determine the value of x is x² + 5x - 36 = 0.
To answer the question, we need to know what equations are
<h3>What is an equation?</h3>
An equation is an expression which shows the relationship between two variables.
Given that the x represents the length of side of the square picture and the rectangular sheet poster leaving a border around the picture of 2 inches on the bottom and 1 inch on each remaining sides.
Then,
- The width of the rectangular poster is W = x + 2 + 1 = x + 3.
- The length of the rectangular poster is L = x + 1 + 1 = x + 2
So, the area of the rectangular sheet poster is A = LW
= (x + 2)(x + 3)
Since the rectangular sheet poster has an area of 42 square inches, A = 42 in².
So, (x + 2)(x + 3) = 42
x² + 3x + 2x + 6 = 42
x² + 5x + 6 - 42 = 0
x² + 5x - 36 = 0
So, an equation that can be used to determine the value of x is x² + 5x - 36 = 0.
