Answer:
look down + pls give me brainiest
Step-by-step explanation:
Let x = number of people when she got on.
x -4+3 -5+1 -1 = 4
x -6 = 4
Solve for x to get x=10.
So there were 10 people when Paulina got on (including herself).
first multiply 14•3 = 42
find 2 numbers that when multiplied it equals to 42 and when added it equals to 23, in this case the numbers are 21 & 2
replace the 23d with the 2 numbers
factor out 3d from the expression
then factor out 2 from the expression
factor out (d+7)
Intersecting, as they would have one solution.
