➷ You have to find a value that, when added to -4, gives -1

This value is +3

The factored form would be (x - 4)(x + 3)

Expand this out:

x^2 + 3x - 4x - 12

==> x^2 -x -12 = 0

w = -12

➶ Hope This Helps You!

➶ Good Luck (:

Which situation is respresented by the inequality below

mihalych1998 [28]

X = greater than or equal to six

Because you divide the 6 from each side

6x > 36
-----------
6. 6

Which equals x = greater than or equal to six

It has to be greater than or equal to because it had the line under it which means equal to and has the open mouth of the comparison sign facing the left which is greater than. Combine them together
