(x + x² + 4x) 3
3(x) + 3(x²) + 3(4x)
3x + 3x² + 12x
Let x be how many hot dogs person b ate
therefore, person a ate x+8 hotdogs
and person c ate x-10 hotdogs
they all ate 130 hotdogs in total so
x + x + 8 + x - 10 = 130
3x -2 = 130
3x = 132
x = 44
so person b ate 44 hotdogs
person a ate 8 more so 52 hotdogs
and person c ate 10 less than person b so 34 hotdogs
Hypothenuse is the longest side
You can see the X is the longest
Solution: A. X
Part A:
We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.
Part B:
As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.
Answer:
Dividend

Divisor

The rule of division of polynomial which is same as division of real numbers states that
Dividend = Divisor × Quotient + Remainder
The division process is shown below.
Quotient = x+5
Remainder =0
