Find a polymonial, which when added to the polynomial 3x^2+3x-1, is equivilant to the following expressions: x+5 PLSSS HELP I NEED IT QUICK WILL MARK BRAINLIEST
1

Step-by-step explanation:

3x² + 3x - 1

should turn into x + 5.

so, let's subtract (x + 5), and the result is then what we have to add in negative version to the original expression (like with subtractions and additions if regular numbers).

3x² + 3x - 1 - x - 5 = 3x² + 2x - 6

so, we need to add -(3x² + 2x - 6) = -3x² - 2x + 6

answer: the common difference is -0.10

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
