Which graph shows the solution to the inequality -3x-7< 20

-3x - 7 < 20
-3x < 20 + 7
-3x < 27
x > -27/3
x > - 9
open circle on -9, shaded to the right

The graph in the attached figure

Step-by-step explanation:

we have

solve for x

-----> Multiply by

The solution is the interval--------> (-9, ∞)

All real numbers greater than ( the number is not included)

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
