Identify the independent and dependent variables. The equation A=25w gives the area A (in square feet) of a rectangular dance fl

kozerog [31]

Answer:

The dependent variable is A

The independent variable is w

Step-by-step explanation:

Given

$A = 25w$

Required

Identify the variables

In $A = 25w$

The value of w is independent of the value of A.

In other words:

A derive its own value from w; by multiplying 25 and w.

Take for instance:

$w = 3$

The value of A would be:

$A = 25 * 3$

$A = 75$

Hence:

The dependent variable is A

The independent variable is w

4(2x + 3) = 5x + 3x - 6

Likurg_2 [28]

Answer:

No solution.

Step-by-step explanation:

$4\left(2x+3\right)=5x+3x-6\\4\left(2x+3\right)=8x-6\\4\left(2x+3\right)\\(a=4,\:b=2x,\:c=3)\\=4\cdot \:2x+4\cdot \:3\\=8x+4\cdot \:3\\=8x+12\\8x+12=8x-6\\8x+12-12=8x-6-12\\0=-18$

If the final answer is 0 and both sides of this equation are unbalanced, that means there will be no solution.
