6.3r < -45.36 which graph shows the correct soultion
skelet666 [1.2K]

6.3 r < -45.36

Here first we have to solve for r and for that we need to get rid of 6.3 .

To get rid of 6.3, we divide both sides by 6.3 that is

r < -7.2

So the solution is all the values which are less then -7.2

And for graph, we put a blank circle or a parenthesis that is () on -7.2 and extend a line to the left side since the inequality is less then .

In 14 the perimeter of the figure Is given. find the length of the indicated side
olga2289 [7]

3x - 7

The perimeter is the sum of all 3 sides of the triangle

To find the third side subtract the sum of the 2 known sides from the perimeter

x + 3 + 2x + 4 = 3x + 7

third side = 6x - (3x + 7 ) = 6x - 3x - 7 = 3x - 7
