No solution.

Step-by-step explanation:

1) Simplify 2 + 2 to 4.

4 + 5 = 0

2) Simplify 4 + 5 to 9.

9 = 0

3) Since 9 = 0 is false, these is no solution.

Can the sides of a triangle have lengths 6.2, 0.5, and 7.8?<br> yes or no
Vitek1552 [10]
No, it's not possible for the sides of a triangle to have those lengths.

According to the triangle inequality theorem, the sum of any two sides of the triangle has to be bigger than the last side. Let's test this.

6.2+7.8\ \textgreater \ 0.5

This inequality satisfies the triangle inequality theorem.

7.8+0.5\ \textgreater \ 6.2

This also satisfies the theorem.

6.2+0.5 \textless \ 7.8

Uh oh. This does not satisfy the triangle inequality theorem. Thus, it is not possible for a triangle to have these side lengths.

How can you represent all of the solutions to systems of inequalities?​
Dimas [21]

Answer:A closed, or shaded, circle is used to represent the inequalities greater than or equal to (≥) or less than or equal to (≤) . The point is part of the solution. An open circle is used for greater than (>) or less than (<). The point is not part of the solution. Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So I graph each inequality, and then find the overlapping portions of the solution regions.Step 1: Line up the equations so that the variables are lined up vertically. Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same. Step 3: Subtract the two equations. Step 4: Solve the one variable system.

Step-by-step explanation:

hope this helps have a great night ❤️❤️❤️
