Which of these is a simplified form of the equation 15x + 4 = 5 + 3x + 1x? (2 points)
Mars2501 [29]

Answer:

11x=1

Step-by-step explanation:

15x+4=5+3x+1x       Bring everything with an x in front of it to the left side

15x-3x-1x+4=5         Simplify the x values

11x+4=5                    Bring the 4 to the right side

11x=5-4

11x=1

The formula=A+2lh+2wh gives surface area a. Of a rectangler solid with length, width, and height, L,W, and H, respectively solve
iogann1982 [59]

Answer:

l= \frac{A}{2h} -w

Step-by-step explanation:

The question is not correct (particularly the expression for the area)

 A=2lh+2wh

Now we are expected to solve for l, that is we are going to make l subject of the formula, we have

let us take the second term on the RHS to the LHS

A-2wh= 2lh

we can now divide both sides by 2h we have

\frac{A-2wh}{2h} = l\\\\l=\frac{A}{2h} -\frac{2wh}{2h} \\\\l= \frac{A}{2h} -w

hence the expression for the length is  l= \frac{A}{2h} -w
