Answer fast ill give brainliest and explain the answer

Step-by-step explanation:

(3x² + 2x + 3 ) + (x² + x +1) = 3x² + 2x + 3  + x² + x +1

              = 4x² + 3x + 4

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
