What is an algebraic expression to represent the perimeter of a rectangle with a width of x+5 and a length of 3x+10?

1 answer:

5 0

We know that the area of a rectangle is equal to the width multiplied by the length. So in this case the algebraic expression is (x+5)*(3x+10). You get 3x^2 +10x +15x +50= 3x^2 +25x +50.

Tell whether the system has one solution, infinitely many solutions, or no solution.

nadya68 [22]

X=-7y+34
x+7y=32

To begin with make the two problems the same kind of problem. By adding 7y on both sides for the first problem.
x+7y=34
x+7y=32

So the correct answer would be no solution because it's the same problem and it can't equal to different answers.
